Vertically Centering Elements Using CSS Techniques
Centering elements vertically within a div can be achieved using various CSS methods. Here are two common approaches:
Flexbox Method
Flexbox provides a versatile layout system that allows for flexible item alignment. To vertically center elements using Flexbox, follow these steps:
- Set the parent container to have a flex display using display: flex.
- Specify a flex-direction of column to stack elements vertically.
- Align items vertically using justify-content: center.
For example, here's a CSS snippet using Flexbox:
#container {
display: flex;
flex-direction: column;
justify-content: center;
}
Table and Positioning Method
This method utilizes the table display and positioning:
- Set the body to a display: table to establish the table-like structure.
- Set the parent container to display: table-cell and vertical-align: middle to align the content vertically.
- Center the elements using margin: 0 auto.
Here's the CSS code for this method:
body {
display: table;
}
#container {
display: table-cell;
vertical-align: middle;
}
.box {
margin: 0 auto;
}
Which Method to Choose?
Flexbox is generally preferred due to its simplicity, efficiency, and wide range of layout options. However, if support for older browsers is a concern, the table and positioning method can be adopted.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

What is the scope of a CSS Custom Property?
Jun 25, 2025 am 12:16 AM
The scope of CSS custom properties depends on the context of their declaration, global variables are usually defined in :root, while local variables are defined within a specific selector for componentization and isolation of styles. For example, variables defined in the .card class are only available for elements that match the class and their children. Best practices include: 1. Use: root to define global variables such as topic color; 2. Define local variables inside the component to implement encapsulation; 3. Avoid repeatedly declaring the same variable; 4. Pay attention to the coverage problems that may be caused by selector specificity. Additionally, CSS variables are case sensitive and should be defined before use to avoid errors. If the variable is undefined or the reference fails, the fallback value or default value initial will be used. Debug can be done through the browser developer
