Here is an example of my HTML and CSS:
<div id="login-light" class="bg-green"></div>
In my CSS, I have defined the following styles:
#login-light {
background-color: red;
}
.bg-green {
background-color: green;
}
I would like to know how to make the element's background color green when it has the class .bg-green. I understand that the CSS for an id takes precedence over a class. Is there a way to achieve this without using JavaScript?
Include a different selector that demonstrates more specificity:
#login-light.bg-green {
background-color: green;
}
For more information on specificity in CSS, check out HTMLDog. A key takeaway is that an ID selector holds more weight than a class selector.
Understanding Specificity
Calculating the specificity of nested selectors involves assigning values: 100 for an ID selector (“#whatever”), 10 for a class selector (“.whatever”), and 1 for an HTML selector (“whatever”). By adding these values together, you can determine the overall specificity value.
p has a specificity of 1 (1 HTML selector) div p has a specificity of 2 (2 HTML selectors, 1+1) .tree has a specificity of 10 (1 class selector) div p.tree has a specificity of 12 (2 HTML selectors + a class selector, 1+1+10)
