Why Does My CSS Sticky Footer Cause Unwanted Scrollbars and Background Issues?

Understanding the Issue with CSS Sticky Footers
Implementing a CSS sticky footer can introduce undesirable scrollbars and cause content to extend beyond its container. Additionally, the background image may not fully cover the page.
To address this, let's examine the provided HTML and CSS code:
HTML:
<div>
CSS:
#content {
height:100%;
min-height:100%;
}
The Issue:
The problem arises from setting both height and min-height to 100%. This fixes the content area to a particular height, preventing it from expanding beyond its specified dimensions. However, the content within the content div may exceed its specified height, resulting in overflow and scrollbars.
Solution 1: CSS Tricks Sticky Footer Snippet
Visit the CSS Tricks website to obtain a code snippet specifically designed for creating sticky footers using CSS.
html, body { height:100%; }
#wrapper { min-height:100%; position:relative; }
#footer { position:absolute; bottom:0; width:100%; }
Solution 2: jQuery Sticky Footer Snippet
If using jQuery is an option, CSS Tricks also provides a jQuery-based sticky footer snippet:
$(document).ready(function() {
var footer = $("#footer");
var pos = footer.position();
var height = $(window).height();
footer.css({
top: height - pos.bottom
});
});
By implementing these solutions, the sticky footer behavior can be achieved while allowing the content area to expand dynamically based on its content, eliminating the unwanted scrollbars and ensuring the background image fully covers the page.

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.
