There is a class B element that has the following CSS applied:
.B{ display:none; }
Then, there is a class A element with the following CSS effect when hovered over:
A:hover .B{ display:block; }
The desired outcome is to make the class B element appear when hovering over the class A element. Is this approach correct? However, it seems like it's not working as expected. Thank you in advance for any assistance.
Your CSS appears to be functioning correctly.
However, if .B is the sole element within .A, it's possible that the visible dimensions of .A will be 0px x 0px.
As a result, the :hover pseudo-class may not activate as expected.
To address this, you have the option to adjust the size of .A using CSS or by inserting an invisible element inside to expand its dimensions.
If you're looking to style specific elements within the DOM tree, CSS alone won't cut it - JavaScript is your best bet for achieving this customization.
Your CSS code appears to be accurate, however it is essential that the corresponding HTML structure is in place for the CSS to work effectively.
<div class="containerA">
<div class="containerB">
</div>
</div>
If your HTML does not match the structure outlined above, consider utilizing jQuery instead.
In order for it to function properly, the .B class must be a child of the .A class.
For example, in this link , it works because .B is a child of .A. However, in this link , it does not work because .B is not a child of .A.
View the working demo here:
To make this work, .B should either be nested within .A or placed next to it in the DOM. You can experiment with the following CSS:
.A:hover + .B {
display:block;
}
Feel free to try it out on this demo:
If this arrangement is not feasible, then using some JavaScript (jQuery) will be necessary:
$(".A").hover(function(){ $(".B").show() },function(){ $(".B").hide() });
One possible solution is to utilize jQuery:
$(document).ready(function(){
$(".A").hover(function(){
$(".B").css("display", "block");
});
});
Alternatively, you can also opt for this approach:
$(document).ready(function(){
$(".A").mouseenter(function(){
$(".B").css("display", "block");
});
$(".A").mouseleave(function(){
$(".B").css("display", "none");
});
});
