Making a Div Stick to the Top of the Screen While Scrolling
Creating a div that remains fixed at the top of the screen after a certain scroll threshold can be achieved using CSS or JavaScript.
CSS Solution
Using CSS, you can position the div as fixed once its top edge reaches the top of the screen:
.fixed-div {
position: fixed;
top: 0;
width: 100%;
z-index: 100;
}
JavaScript Solution
With JavaScript, you can dynamically change the position of the div when the scroll position reaches a specific value:
$(window).scroll(function(e) {
var $div = $('.fixed-div');
var scrollTop = $(this).scrollTop();
if (scrollTop > 200) {
$div.css('position', 'fixed');
$div.css('top', '0');
} else {
$div.css('position', 'static');
$div.css('top', '0');
}
});
In this script, the jQuery scroll() function is used to listen for scroll events. When the scrollTop position exceeds 200, the div is given a fixed position and set to the top of the page. When the scrollTop drops below 200, the div reverts back to a static position.

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.
