What is the proper way to utilize li.class:hover in CSS code?

When trying to apply a class to an li element during a hover event, I encountered some difficulties. Below is the code that works without the class:

#leaderboard li:hover {
    z-index:1000;
    -webkit-transform: scale(3.2);
    -moz-transform: scale(3.2);
    -ms-transform: scale(3.2);
    -o-transform: scale(3.2);
    transform: scale(3.2);    
}

However, the following code does not work as expected:

#leaderboard li.0:hover {
    z-index:1000;
    -webkit-transform: scale(1.1);
    -moz-transform: scale(1.1);
    -ms-transform: scale(1.1);
    -o-transform: scale(1.1);
    transform: scale(1.1);    
}

Here is the HTML snippet:

<ul id="leaderboard" name="leaderboard">
<li class="0" style="left: 0px;"><h1 style="display:inline" id="user-234">4900</h1> <img style="height:50px" src="serveurtopmc.jpg"> xxx</li>
... (continued list items)

If anyone knows the correct syntax for this issue, please share it with me :)

==========

After some trial and error, I was able to successfully implement the solution thanks to mcabrams! It involved using the selector #leaderboard li.rank0:hover. Good to go now!

Answer №1

Should the category need to stay numerical, one can utilize the Unicode code point for zero: code sample

#table li.\30:hover {
    background-color: salmon;
}

Answer №2

To solve this issue, consider targeting the selector as #leaderboard li.\30:hover - taking advantage of Unicode's representation of the number 0 (\30 -> 0). Alternatively, you can apply a similar rule for the 10 class by using #leaderboard li.\31\0:hover. Another option is to rename the class so it does not start with a number.
