Why Does Firefox Ignore Padding When Using Overflow: Scroll?
Oct 25, 2024 pm 04:20 PMFirefox Ignores Padding When Using Overflow: Scroll
When using overflow: scroll with padding styles, a puzzling issue arises in Firefox: the bottom padding of the element vanishes. This behavior is observed in both direct and inherited padding scenarios.
Cause:
The exact cause of the issue is unknown, but it appears to stem from Firefox's rendering behavior where overflowed content is clipped without considering the padding.
Workaround:
To compensate for this inconsistency, a pure CSS solution can be implemented:
<code class="css">.container:after { content: ""; height: 50px; display: block; }</code>
Explanation:
This CSS snippet adds an empty pseudo-element after the container. By setting its height to the same value as the bottom padding and setting display to block, it creates an invisible buffer that forces Firefox to respect the padding.
Limitations:
While this workaround resolves the issue, it does introduce a caveat:
- If the content within the scrollable container overflows beyond the height of the container, the additional pseudo-element height will be visible.
To avoid this, you can use JavaScript to dynamically adjust the height of the pseudo-element based on the height of the overflowed content, ensuring that it remains hidden while accommodating the padding.

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.

Autoprefixer is a tool that automatically adds vendor prefixes to CSS attributes based on the target browser scope. 1. It solves the problem of manually maintaining prefixes with errors; 2. Work through the PostCSS plug-in form, parse CSS, analyze attributes that need to be prefixed, and generate code according to configuration; 3. The usage steps include installing plug-ins, setting browserslist, and enabling them in the build process; 4. Notes include not manually adding prefixes, keeping configuration updates, prefixes not all attributes, and it is recommended to use them with the preprocessor.

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.
