Fixing Table Headers with Scrolling Body
Maintaining fixed table headers while allowing the body to scroll is a common requirement in web development. To achieve this, employ the following approach:
1. Wrap Table Content in Two Nested Elements:
- Create an outer table element (e.g., #mainTable) to hold the entire table.
- Create an inner table element (e.g., #innerTable) to contain the table body that needs to scroll.
2. Set Outer Table Height:
- Apply a fixed height to the outer table using CSS (e.g., #mainTable { height: 500px; }).
3. Position Inner Table:
- Position the inner table absolutely within the outer table using CSS (e.g., #innerTable { position: absolute; top: 0; bottom: 0; width: 100%; }).
4. Fix Headers:
- Apply position: sticky; to the header rows of the inner table (e.g., #innerTable th { position: sticky; top: 0; }).
5. Enable Scrolling:
- Ensure the inner table's height exceeds the outer table's height, triggering vertical overflow.
- Enable scrolling on the inner table using CSS (e.g., #innerTable { overflow: auto; }).
Example:
<div>

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.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
