How to Scroll a Fixed Position Div Horizontally with Content Using jQuery
To ensure a fixed div scrolls horizontally with the content, a combination of CSS and jQuery code is necessary. Here's how to implement it:
CSS
<code class="css">.scroll_fixed {
position: absolute;
top: 210px;
}
.scroll_fixed.fixed {
position: fixed;
top: 0;
}</code>
jQuery
<code class="javascript">// Retrieve the initial left offset
var leftInit = $(".scroll_fixed").offset().left;
// Get the top offset of the div
var top = $('.scroll_fixed').offset().top - parseFloat($('.scroll_fixed').css('margin-top').replace(/auto/, 0));
$(window).scroll(function(event) {
// Calculate the horizontal scroll position
var x = 0 - $(this).scrollLeft();
// Calculate the vertical scroll position
var y = $(this).scrollTop();
// Position the div based on scroll
// Horizontally: Left margin of the initial position minus the horizontal scroll position
// Vertically: Top margin of the initial position minus the vertical scroll position
if (y >= top) {
// Display the div at the top of the viewport
$('.scroll_fixed').addClass('fixed');
} else {
// Remove the 'fixed' class from the div
$('.scroll_fixed').removeClass('fixed');
}
$(".scroll_fixed").offset({
left: x + leftInit,
top: y
});
});</code>
This code manages the horizontal scrolling by adjusting the left property of the div, ensuring that it remains synchronized with the content. The leftInit variable incorporates possible left margins to enhance the function's accuracy.

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.
