Creating a Horizontal Scrollbar on Both the Top and Bottom of a Table
In cases where a large table extends beyond the visible browser window, it's often desirable to have scrollbars on both the top and bottom to navigate the entire table content efficiently.
In pure HTML and CSS, this can be achieved by simulating a second horizontal scrollbar at the top. Here's how:
-
Create a Dummy Div:
Add a div element above the table and style it with a height sufficient to create the appearance of a scrollbar (e.g., 20px).
-
Disable Vertical Scrolling:
Set overflow-y: hidden for both the dummy div and the table's parent div to restrict scrolling to the horizontal axis.
-
Enable Horizontal Scrolling:
Set overflow-x: scroll for the dummy div and the table's parent div to enable horizontal scrolling in both areas.
-
Synchronize Scrollbars:
Utilize JavaScript to synchronize the scrolling of the dummy div and the table by attaching event listeners to the scroll event. When one scrollbar is moved, the other one adjusts accordingly.
Here's an example that puts a dummy div on top of the table's parent div:
HTML:
<div class="table-wrapper"> <div class="dummy-scrollbar"></div> <div class="data-table">
CSS:
.table-wrapper {
height: 130%;
overflow: auto;
width: 100%;
}
.dummy-scrollbar {
height: 20px;
width: 100%;
overflow-x: scroll;
overflow-y: hidden;
}
.data-table {
overflow-x: scroll;
overflow-y: visible;
width: 100%;
}
JavaScript:
$(".table-wrapper").scroll(function() {
$(".dummy-scrollbar").scrollLeft($(this).scrollLeft());
});
$(".dummy-scrollbar").scroll(function() {
$(".table-wrapper").scrollLeft($(this).scrollLeft());
});
By implementing this approach, you can create the illusion of a second horizontal scrollbar on top of your table, enhancing navigation and accessibility.

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.

What is the scope of a CSS Custom Property?
Jun 25, 2025 am 12:16 AM
The scope of CSS custom properties depends on the context of their declaration, global variables are usually defined in :root, while local variables are defined within a specific selector for componentization and isolation of styles. For example, variables defined in the .card class are only available for elements that match the class and their children. Best practices include: 1. Use: root to define global variables such as topic color; 2. Define local variables inside the component to implement encapsulation; 3. Avoid repeatedly declaring the same variable; 4. Pay attention to the coverage problems that may be caused by selector specificity. Additionally, CSS variables are case sensitive and should be defined before use to avoid errors. If the variable is undefined or the reference fails, the fallback value or default value initial will be used. Debug can be done through the browser developer
