CSS-Only Scrollable Table with Fixed Headers
In this question, the user seeks to create scrollable tables with fixed headers and footers using CSS only. Their specific requirements include:
- Preserving column alignment between header, footer, and content rows
- Keeping the header and footer fixed while allowing the content to scroll vertically
- Accomplishing this solely with HTML table tags and CSS rules

However, certain browsers (e.g., Chrome, IE, Edge) have encountered issues when assigning position: sticky to table header rows ( or To achieve the desired effect, the user can consider the following code: This code wraps the table in a div with overflow: auto to establish a scrollable area. The table headers are assigned a sticky position, ensuring they remain fixed as the content scrolls vertically.

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.

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.
