Красивая ошибка css

Welcome to a quick tutorial on how to create custom error messages with pure CSS. By now, you should have experienced the intrusive default Javascript alert box. Every time it shows up, users get scared away.

<div style="border: 1px solid darkred; background: salmon">
  <i>&#9888;</i> ERROR!
</div>

Yep, it is that simple. Let us “improve and package” this simple error notification bar so you can reuse it easily in your project – Read on!

ⓘ I have included a zip file with all the source code at the start of this tutorial, so you don’t have to copy-paste everything… Or if you just want to dive straight in.

QUICK NOTES

If you spot a bug, feel free to comment below. I try to answer short questions too, but it is one person versus the entire world… If you need answers urgently, please check out my list of websites to get help with programming.

EXAMPLE CODE DOWNLOAD

Click here to download the source code, I have released it under the MIT license, so feel free to build on top of it or use it in your own project.

1) BASIC NOTIFICATION BAR

1A) THE HTML

1-basic.html

<div class="bar">Plain message</div>
<div class="bar info">Information message</div>
<div class="bar success">Successful message</div>
<div class="bar warn">Warning message</div>
<div class="bar error">Error message</div>

That is actually all we need to create a custom error message, an HTML <div> with the notification message inside. Take note of the bar and info | success | warn | error CSS classes – We will use these to build the notification bar.

1B) THE CSS

error-bar.css

/* (A) THE BASE */
.bar {
  padding: 10px;
  margin: 10px;
  color: #333;
  background: #fafafa;
  border: 1px solid #ccc;
}

/* (B) THE VARIATIONS */
.info {
  color: #204a8e;
  background: #c9ddff;
  border: 1px solid #4c699b;
}
.success {
  color: #2b7515;
  background: #ecffd6;
  border: 1px solid #617c42;
}
.warn {
  color: #756e15;
  background: #fffbd1;
  border: 1px solid #87803e;
}
.error {
  color: #ba3939;
  background: #ffe0e0;
  border: 1px solid #a33a3a;
}

The CSS is straightforward as well –

• .bar is literally the “basic notification bar” with padding, margin, and border.
• .info | .success | .warn | .error sets various different colors to fit the “level of notification”.

Feel free to changes these to fit your own website’s theme.

1C) THE DEMO

2) ADDING ICONS

2A) THE HTML

2-icon.html

<div class="bar">
  <i class="ico">&#9728;</i> Plain message
</div>
<div class="bar info">
  <i class="ico">&#8505;</i> Information message
</div>
<div class="bar success">
  <i class="ico">&#10004;</i> Successful message
</div>
<div class="bar warn">
  <i class="ico">&#9888;</i> Warning message
</div>
<div class="bar error">
  <i class="ico">&#9747;</i> Error message
</div>

To add icons to the notification bar, we simply prepend the messages with <i class="ico">&#XXXX</i>. For those who do not know – That &#XXXX is a “native HTML symbol”, no need to load extra libraries. Do a search for “HTML symbols list” on the Internet for a whole list of it.

P.S. Check out Font Awesome if you want more icon sets.

2B) THE CSS

error-bar.css

/* (C) ICONS */
i.ico {
  display: inline-block;
  width: 20px;
  text-align: center; 
  font-style: normal;
  font-weight: bold;
}

Just a small addition to position the icon nicely.

2C) THE DEMO

3) ADDING CLOSE BUTTONS

3A) THE HTML

3-close.html

<div class="bar">
  <div class="close" onclick="this.parentElement.remove()">X</div>
  <i class="ico">&#9728;</i> Plain message
</div>
<div class="bar info">
  <div class="close" onclick="this.parentElement.remove()">X</div>
  <i class="ico">&#8505;</i> Information message
</div>
<div class="bar success">
  <div class="close" onclick="this.parentElement.remove()">X</div>
  <i class="ico">&#10004;</i> Successful message
</div>
<div class="bar warn">
  <div class="close" onclick="this.parentElement.remove()">X</div>
  <i class="ico">&#9888;</i> Warning message
</div>
<div class="bar error">
  <div class="close" onclick="this.parentElement.remove()">X</div>
  <i class="ico">&#9747;</i> Error message
</div>

Not much of a difference here, except that we now add a <div class="close"> that will act as the close button.

3B) THE CSS

error-bar.css

/* (D) CLOSE BUTTON */
.bar { position: relative; }
div.close {
  position: absolute;
  top: 30%;
  right: 10px;
  color: #888;
  cursor: pointer;
}

There is not much added to the CSS as well. We simply position the close button to the right of the notification bar, and that’s about it.

3C) THE DEMO

4) PACKAGED ERROR NOTIFICATIONS

4A) THE HTML

4-js.html

<!-- (A) LOAD CSS + JS -->
<link href="error-bar.css" rel="stylesheet">
<script src="error-bar.js"></script>
 
<!-- (B) HTML CONTAINER -->
<div id="demo"></div>

 <!-- (C) FOR TESTING -->
<script>
let demo = document.getElementById("demo");
ebar({ target: demo, msg: "Plain" });
ebar({ lvl: 1, target: demo, msg: "Information" });
ebar({ lvl: 2, target: demo, msg: "Success" });
ebar({ lvl: 3, target: demo, msg: "Warning" });
ebar({ lvl: 4, target: demo, msg: "Error" });
</script>

The notification bar is has gotten rather messy, and it is a pain to manually copy-paste them. So why not package everything into an easy-to-use Javascript ebar() function?

• target Target HTML container to generate the error message.
• msg The error or notification message.
• lvl Optional, error level.

4B) THE JAVASCRIPT

error-bar.js

function ebar (instance) {
// target : target html container
// msg : notification message
// lvl : (optional) 1-info, 2-success, 3-warn, 4-error
 
  // (A) CREATE NEW NOTIFICATION BAR
  let bar = document.createElement("div");
  bar.classList.add("bar");
 
  // (B) ADD CLOSE BUTTON
  let close = document.createElement("div");
  close.innerHTML = "X";
  close.classList.add("close");
  close.onclick = () => bar.remove();
  bar.appendChild(close);
 
  // (C) SET "ERROR LEVEL"
  if (instance.lvl) {
    let icon = document.createElement("i");
    icon.classList.add("ico");
    switch (instance.lvl) {
      // (C1) INFO
      case 1:
        bar.classList.add("info");
        icon.innerHTML = "ℹ";
        break;
 
      // (C2) SUCCESS
      case 2:
        bar.classList.add("success");
        icon.innerHTML = "☑";
        break;
 
      // (C3) WARNING
      case 3:
        bar.classList.add("warn");
        icon.innerHTML = "⚠";
        break;
 
      // (C4) ERROR
      case 4:
        bar.classList.add("error");
        icon.innerHTML = "☓";
        break;
    }
    bar.appendChild(icon);
  }
 
  // (D) NOTIFICATION MESSAGE
  let msg = document.createElement("span");
  msg.innerHTML = instance.msg;
  bar.appendChild(msg);
 
  // (E) ADD BAR TO CONTAINER
  instance.target.appendChild(bar);
}

This may look complicated, but this function essentially just creates all necessary notification bar HTML.

Our Awesome Tools

#01: Lenny Face

#02: Fancy Text Generator

This tutorial will show you how to create and customize error messaging for various form elements. In this tutorial, we will customize everything from a basic error message to input field errors and tooltips. The best part? We will be using only CSS for customizations – that means no images or javascript required!

HTML

Below is the markup for the form elements we will be creating error messaging for. This is all of the HTML used throughout this tutorial. Copy and paste this code into your working file:

<!-- Basic Error Message -->
<div class="error-message">
  <span class="error-text">Checkout could not be completed. Please check your login information and try again.</span>
</div>
 
<!-- Input Field Error -->
<div class="input-group error">
  <label>Password *</label> 
  <input type="text">
  <div class="error-message">Password is a required field.</div>
</div>
 
<!-- Input Field Error with Tooltip -->
<div class="input-group error">
  <label>Quantity</label> 
  <input type="text">
  <div class="error-tip">Enter a quantity</div>
</div>

CSS

Now onto my personal favorite: the CSS. We will keep the basic functionality of the form elements but completely customize their appearance. In the end, they will stand on their own as custom design elements that thoughtfully guide the user through the form process, making it as straightforward and painless as possible.

Basic Error Message

Let’s start with a basic error message. We are going to customize the HTML above to look like this:

This is what we start out with, by default, after adding the HTML:

Customizing a basic error message is really simple. All we have to do is give our text a colored background and a couple font styles using CSS. To style the error message background, add the following styles to your CSS stylesheet:

.error-message {
  background-color: #fce4e4;
  border: 1px solid #fcc2c3;
  float: left;
  padding: 20px 30px;
}

Now let’s style the text itself by adding the following font styles:

.error-text {
  color: #cc0033;
  font-family: Helvetica, Arial, sans-serif;
  font-size: 13px;
  font-weight: bold;
  line-height: 20px;
  text-shadow: 1px 1px rgba(250,250,250,.3);
}

That’s it! Keep reading to learn how to style input field and tooltip errors.

Input Field Error

Now that we have our basic error message styled, let’s work on input field errors. This is what the final product will look like:

And this is what we start out with by default:

First, we want to override the browser’s default styles. Add the following CSS to give your input field a custom look:

/* Basic Input Styling */
.input-group {
  color: #333;
  float: left;
  font-family: Helvetica, Arial, sans-serif;
  font-size: 13px;
  line-height: 20px;
  margin: 0 20px 10px;
  width: 200px;
}

label {
  display: block;
  margin-bottom: 2px;
}

input[type=text] {
  background: #fff;
  border: 1px solid #999;
  float: left;
  font-size: 13px;
  height: 33px;
  margin: 0;
  padding: 0 0 0 15px;
  width: 100%;
}

Next, we need to add the styling for the error message that displays when a user does not correctly fill out an input field (i.e. the “This is a required field” message):

.error-message {
  color: #cc0033;
  display: inline-block;
  font-size: 12px;
  line-height: 15px;
  margin: 5px 0 0;
}

Lastly, add the error-specific styling for the input field elements:

.error label {
  color: #cc0033;
}

.error input[type=text] {
  background-color: #fce4e4;
  border: 1px solid #cc0033;
  outline: none;
}

Input Field Error with Tooltip

The last element we’re tackling is the tooltip. It is slightly more complicated than the others but well worth the effort. We will also be utilizing Sass nesting to better organize our code, and because we are only using SCSS it is 100% editable and scalable.

Once we are done, the tooltip will look like this:

And by default, this is what we start with after adding the HTML:

First, we override the browser’s default styles with our own custom styling:

/* Basic Input Styling */
.input-group {
  color: #333;
  float: left;
  font-family: Helvetica, Arial, sans-serif;
  font-size: 13px;
  line-height: 20px;
  margin-bottom: 10px;
  width: 100%;
}

label {
  display: block;
  margin-bottom: 5px;
}

input[type=text] {
  background: #fff;
  border: 1px solid #ccc;
  color: #333;
  float: left;
  font-family: Helvetica, Arial, sans-serif;
  font-size: 13px;
  height: 33px;
  line-height: 20px;
  margin: 0;
  padding: 0 0 0 15px;
  width: 45px;
}

Just like our previous example, we need to add the tooltip error message styling that displays when a form error occurs. Note: we are using Sass here to nest the tooltip’s left arrow properties. This comes in handy when trying to keep track of which values are assigned to the tooltip specifically:

/* Tooltip Styling */
.error-tip {
  background-color: #fce4e4;
  border: 1px solid #fcc2c3;
  border-radius: 7px;
  -moz-border-radius: 7px;
  -webkit-border-radius: 7px;
  display: inline;
  color: #cc0033;
  float: left;
  font-weight: bold;
  line-height: 24px;
  position: relative;
  padding: 7px 11px 4px;
  margin-left: 17px;
  // Left Arrow Styling Starts Here
  &:after, &:before {
    content: '';
    border: 7px solid transparent;
    position: absolute;
    top: 11px;
  }
  &:after {
    border-right: 7px solid #fce4e4;
    left: -14px;
  }
  &:before {
    border-right: 7px solid #fcc2c3;
    left: -15px;
  }
} // end .error-tip

Now all that’s left to do is define the input’s error-specific styling. Again, we will nest these styles under an “error” class selector to make classification and future changes easier:

/* Error Styling */
.error.input-group {
  label {
    color: #cc0033;
    font-weight: bold;
  }
  input {
    border: 2px solid #cc0033;
    line-height: 37px;
    outline: none;
  }
  .status {
    display: none;
  }
  .error-tip {
    display: inline;
  }
} // end .error

And that’s it! All the code you need to customize error messaging for default form elements. To experiment with the final results and copy and paste to your heart’s content (without fear of breaking anything), jump on over to Codepen by selecting any of the tutorial links below.

Hello readers, Today in this blog you’ll learn how to create a Custom 404 Error Page using only HTML & CSS. Earlier I have shared many blogs related to Web Design like (Responsive Footer Design, Responsive Drop-down Menu, and Responsive Sidebar Menu). But now I’m going to create a 404 Error page which is also a part or section of the Website.

The HTTP 404, 404 Not Found, or 404 Page Not Found error message is a Hypertext Transfer Protocol (HTTP) standard response code, in computer network communications, to indicate that the browser was able to interact with a given server but the server could not locate what was requested. This error displays when the user-requested page or URL doesn’t exist on a particular site.

In this program (Custom 404 Error Page Design), at first, on the webpage, there is a linear-gradient background with a white container box. Inside the box, there is title text, description, and two buttons. That 404 text has a mask animation that means there is gradient-color animation that flows top to bottom. This error page is created only for design purposes and it won’t redirect you to any other page when you click on the buttons.

If you’re feeling difficult to understand what I am saying. You can watch a full video tutorial on this program (Custom 404 Error Page Design).

As you have seen the actual text mask moving animation in the video and I believe you understood the basic codes behind creating this error page. This is a pure CSS program so there are no vast codes used to create this program. Nowadays every website has its custom 404 error page which helps to inform the user about their requested pages are not exist on the website.

You can also create this type of error page and use it on your projects and HTML pages. If you know JavaScript then you can add advanced features to this program and take this program to the next level.

Hello, guys in this tutorial we will create an simple 404 error page template using HTML & CSS, and also i have listed best 404 page not found examples which is are available in codepen.

How to create 404 page not found template using HTML & CSS

Step 1: — Creating a New Project

The first thing we’ll do is create a folder that will contain all of the files that make up the project. Create an empty folder on your devices and name it “as you want”.

Open up Visual Studio Code or any Text editor which is you liked, and create files(index.html, style.css) inside the folder which you have created for 404 error page. In the next step, we will start creating the basic structure of the webpage.

Step 2: — Setting Up the basic structure

In this step, we will add the HTML code to create the basic structure of the project.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8" />
  <title>404 Error Page</title>
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <meta https-equiv="X-UA-Compatible" content="ie=edge" />
  <link rel="stylesheet" href="style.css" />
  <link href="https://fonts.googleapis.com/css2?family=IBM+Plex+Sans:wght@500&display=swap" rel="stylesheet">
  <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">
</head>
<body>
  
</body>
</html>

This is the base structure of most web pages that use HTML.

Add the following code inside the <body> tag:

<div class="wrapper">
  <div class="container">
    <div class="grid-row">
      <div class="colmun colmun-left">
        <img src="image-left.png" alt="image-left">
        <h1 class="px-spc-b-20">We can't find the page you are looking for.</h1>
        <span class="px-spc-b-20">This page has been relocated or removed.</span>

        <button class="go-home"><i class="fa fa-home"></i> Go Home</button>
      </div>
      <div class="colmun colmun-right">
        <img src="right-shape.png" alt="right-shape">
      </div>
    </div>
  </div>
</div>

Step 3: — Adding Styles for the Classes

In this step, we will add CSS code for style our html elements.

* {
  padding: 0;
  margin: 0;
  outline: 0;
  color: #444;
  box-sizing: border-box;
  font-family: 'IBM Plex Sans', sans-serif;
}
body {
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100vh;
  overflow: hidden;
}
h1 {
  font-size: 50px;
  line-height: 60px;
}
span {
  display: block;
  font-size: 18px;
  line-height: 30px;
}
.container {
  width: 80%;
  max-width: 1600px;
  margin: auto;
}
.grid-row {
  display: grid;
  grid-template-columns: 1fr 1fr;
  place-items: center;
  grid-gap: 50px;
}
.colmun-left {
  text-align: left;
}
.colmun-right {
  text-align: right;
}
.px-spc-b-20 {
  padding-bottom: 20px;
}
button.go-home {
  padding: 5px 20px;
  background: #ffa000;
  border: transparent;
  border-radius: 2px;
  box-shadow: 0 0 2px rgb(0 0 0 / 30%);
  cursor: pointer;
  margin: 20px 0;
  color: #fff;
}
button.go-home i {

}
img {
