Maintaining Div at Page Bottom with Scrolling Content
Achieving the effect where a footer remains at the bottom of the page despite scrolling requires a specific approach. While the desired outcome is similar to having a div push to the bottom of the page, the solution is different.
The key lies in understanding the behavior of different CSS positioning options. In this case, position: absolute has been used to move the footer to the bottom of the viewport. However, this positioning remains fixed in relation to the viewport, causing the footer to stay in the same location even when the content scrolls.
To ensure that the div remains at the bottom of the page's content, position: fixed should be used instead:
#footer { position: fixed; bottom: 0; width: 100%; }
With this modification, the footer will be fixed to the bottom of the page, regardless of whether the content overflows. It will scroll along with the content, remaining at the bottom of all visible elements. This behavior is commonly seen on websites like Stack Overflow, where the footer remains at the bottom even when numerous questions and answers are present on the page.
By employing position: fixed, the div will stay at the bottom of the page's contents, adapting to the dynamic height of the page as content scrolls, maintaining the desired layout.

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.

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.
