Tips for changing and resetting a background-color property after a hover effect

Is it possible to remove the background-color property of a :hover rule?

I have a set of elements that change color when hovered over. I want to add another CSS rule to prevent this color change. Here's an example:

http://jsfiddle.net/vqLuU/1/

How can I modify the second instance of the "style1:hover" rule to completely disable the color change effect? The end result should be the same as if all "style1:hover" rules were removed.

I'd like to avoid having to redefine all the styles ("green" and "blue") again. My objective is to simply turn off the "style1:hover" rule.

HTML:

<div class="style1 green">AAA</div>
<div class="style1 blue">BBB</div>

CSS:

.green {
    background-color: green;
}
.blue {
    background-color: blue;
}
.style1:hover {
    background-color: red;
}

.style1:hover {
    /* How do I disable the color change from here? */

}

Thank you!

Answer №1

To make changes to the first appearance of the .style1:hover rule, you can't remove or alter it directly. Instead, we need to introduce additional rules like so:

.green:hover {
    background-color: green;
}
.blue:hover {
    background-color: blue;
}

I must clarify that while this workaround may not be the most elegant solution, it is the only feasible option within the given constraints.

Note: When considering solutions, it's important to remember that the use of JavaScript may be necessary

One possible approach could involve dynamically manipulating the stylesheets using JavaScript to remove the CSS rule. However, this method may not be ideal and other users on Stack Overflow can offer insights or suggestions. A sample implementation of this technique can be found in this jsFiddle example.

for (var i = 0; i < document.styleSheets.length; i++ ) {
    var done = false;
    var sheet = document.styleSheets[i];
    # Some browsers use rules (Chrome) others use cssRules (Firefox)
    var rules = sheet.rules || sheet.cssRules;

    for (var j = 0; j < rules.length; j++) {
        var rule = rules[j];
        var selectorText = rule.selectorText;

        if (selectorText.indexOf(".style1:hover") != -1) {
            sheet.deleteRule(j);
            done = true;
            break;
        }
    }

    if (done) break;
}

Answer №3

.style1:hover {
    background-color: red;
}

.style1:hover {
    background-color: transparent !important;
}

Answer №4

The simplest method that comes to mind for achieving the desired outcome is by appending an additional class to the elements. I have opted for the name 'hoverEnabled'

By adding or removing the hoverEnabled class to an element, you can apply a different style for :hover.

Cascading Style Sheets (CSS)

.green {
    background-color: green;
}
.blue {
    background-color: blue;
}
.style1.hoverEnabled:hover {
    background-color: #FFAAAA;
}

.style2.hoverEnabled:hover {
    background-color: #AAAAAA;
}

HyperText Markup Language (HTML)

<div class="style1 green">AAA</div>
<div class="style1 blue">BBB</div>
<div class="style1 hoverEnabled green">AAA</div>
<div class="style2 hoverEnabled blue">BBB</div>
