In the previous article "HTML/css to achieve a fun text liquid filling effect" I introduced how to use HTML/css to achieve a fun text liquid filling effect. Interested friends can learn Find out~
This article will introduce to you how to use HTML and CSS to create a glass/blur effect overlay.
What is the specific effect?
Let’s go directly to the complete code:
<!DOCTYPE HTML>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
<style>
body {
margin: 0;
padding: 0;
}
section {
position: relative;
background: url(004.jpg);
background-attachment: fixed;
height: 100vh;
}
section .layout {
position: relative;
top: 35%;
left: 30%;
max-width: 600px;
padding: 50px;
box-shadow: 0 10px 20px rgba(0, 0, 0, .5);
color: rgb(255, 254, 254);
}
section .layout::before {
content: '';
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
background: url(004.jpg);
background-attachment: fixed;
filter: blur(8px);
}
section .layout h2 {
position: relative;
}
section .layout p {
position: relative;
}
section .layout button {
position: relative;
}
</style>
</head>
<body>
<section>
<div class="layout">

</p>
<button class="btn btn-outline-danger">
按钮
</button>
</div>
</section>
</body>
</html>The effect is as follows:
Here we mainly need to master the filter attribute and :before selection Filter:
filter attribute:
The filter attribute defines the visual effect (for example: blur and saturation) of the element (usually ).
Note: The non-standard "filter" attribute supported by older versions of Internet Explorer (4.0 to 8.0) has been deprecated. IE8 and lower browsers usually use the opacity attribute.
:before selector:
:before selector inserts content before the content of the selected element. Use the content attribute to specify the content to be inserted.
Note: For :before in IE8 and earlier versions, must be declared.

Updating State Correctly with useState() in ReactApr 29, 2025 am 12:42 AMCorrect update of useState() state in React requires understanding the details of state management. 1) Use functional updates to handle asynchronous updates. 2) Create a new state object or array to avoid directly modifying the state. 3) Use a single state object to manage complex forms. 4) Use anti-shake technology to optimize performance. These methods can help developers avoid common problems and write more robust React applications.
React's Component-Based Architecture: A Key to Scalable UI DevelopmentApr 29, 2025 am 12:33 AMReact's componentized architecture makes scalable UI development efficient through modularity, reusability and maintainability. 1) Modularity allows the UI to be broken down into components that can be independently developed and tested; 2) Component reusability saves time and maintains consistency in different projects; 3) Maintainability makes problem positioning and updating easier, but components need to be avoided overcomplexity and deep nesting.
Declarative Programming with React: Simplifying UI LogicApr 29, 2025 am 12:06 AMIn React, declarative programming simplifies UI logic by describing the desired state of the UI. 1) By defining the UI status, React will automatically handle DOM updates. 2) This method makes the code clearer and easier to maintain. 3) But attention should be paid to state management complexity and optimized re-rendering.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
