Show Div on ScrollDown After 800px Revisited
In this revisited discussion, we aim to refine our approach to showing a hidden div when scrolling down after 800px from the page's top.
Solution:
We employ a straightforward solution using JavaScript's $(document).scroll() function, as follows:
$(document).scroll(function() {
var y = $(this).scrollTop();
if (y > 800) {
$('.bottomMenu').fadeIn();
} else {
$('.bottomMenu').fadeOut();
}
});
Explanation:
- scrollTop retrieves the current vertical scroll position of the page.
- If scrollTop exceeds 800 pixels, the bottomMenu div is made visible using fadeIn().
- Conversely, if scrollTop falls below 800 pixels, bottomMenu is hidden using fadeOut().
Enhancement for Scroll Up:
To enhance this solution, we can add functionality to hide bottomMenu when scrolling up and the scroll height is less than 800px:
if (y < 800 && $('.bottomMenu').css('display') !== 'none') {
$('.bottomMenu').fadeOut();
}
This additional condition ensures that bottomMenu remains hidden when scrolling up and the scroll height is less than 800px.

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.
