CSS Mouse Hover Scroll Bar
In web design, we often encounter the need to display scroll bars when the user hovers the mouse over an element. This interactive effect allows users to clearly see the completeness of the content and provides a better user experience. This article will introduce how to use CSS to achieve the effect of displaying scroll bars when the mouse hovers.
Using the overflow property to control an element’s scrollbars
In CSS, we can use the overflow property to control an element’s scrolling behavior. This property has four possible values: visible (the default), hidden, scroll, and auto. scroll and auto display scrollbars when the content overflows.
Below is a simple example code showing how to use overflow Property showing scroll bar:
<!DOCTYPE html>
<html>
<head>
<style>
.scrollable {
width: 200px;
height: 100px;
border: 1px solid #ccc;
overflow: auto;
}
</style>
</head>
<body>
<div class="scrollable">
<p>This is an element with a scrollbar. This is an element with a scrollbar. This is an element with a scrollbar. This is an element with a scrollbar. </p>
<p>This is an element with a scrollbar. This is an element with a scrollbar. This is an element with a scrollbar. This is an element with a scrollbar. </p>
<p>This is an element with a scrollbar. This is an element with a scrollbar. This is an element with a scrollbar. This is an element with a scrollbar. </p>
<p>This is an element with a scrollbar. This is an element with a scrollbar. This is an element with a scrollbar. This is an element with a scrollbar. </p>
<p>This is an element with a scrollbar. This is an element with a scrollbar. This is an element with a scrollbar. This is an element with a scrollbar. </p>
</div>
</body>
</html>
In the code above, we create a <div> element with scrollbars. When the content overflows, horizontal and vertical scrollbars appear. This allows users to scroll to view the entire content.
Using the hover pseudo-class to achieve a hovering effect
To achieve the effect of displaying scrollbars when the user hovers over an element, we can use the CSS :hover pseudo-class. When the user hovers over a specific element, we display the scrollbars by changing the value of the overflow property.
Here is a sample code that demonstrates how to display scrollbars on mouse hover:
<!DOCTYPE html>
<html>
<head>
<style>
.scrollable {
width: 200px;
height: 100px;
border: 1px solid #ccc;
overflow: hidden;
}
.scrollable:hover {
overflow: auto;
}
</style>
</head>
<body>
<div class="scrollable">
<p>Hovering the mouse over this element with a scrollbar will display the scrollbar. </p>
<p>Hovering the mouse over this element with a scrollbar will display the scrollbar. </p>
<p>Hovering the mouse over this element with a scrollbar will display the scrollbar. </p>
<p>Hovering the mouse over this scrollable element will display the scrollbar. </p>
<p>Hovering the mouse over this scrollable element will display the scrollbar. </p>
</div>
</body>
</html>
In the above code, we apply the .scrollable class to the <div> element. When the user hovers over this element, we set the .scrollable:hover style to change the overflow property to auto, thereby displaying the scrollbar.
Conclusion
Through this article, we learned how to use CSS to control the scrollbars of an element and how to use the :hover pseudo-class to display the scrollbars on hover. This interactive design allows users to more easily view content and improves the user experience.
