In one of my recent projects, I noticed that certain styles occur in the same combination repeatedly. According to the DRY principle, I should combine these styles. Regarding a good CSS style, what option is better/the best?
Option 1
Creating a class that contains these styles and simply add it in the HTML to the according elements.
Example
In the HTML:
<a href='#' class="myClass">Link</a>
or
<ul class="myClass">
<li>Item</li>
<ul>
In the CSS:
.myClass {
font-weight: bold;
font-size: 14px;
color: grey;
}
Option 2
Simply combining all elements that need that style in my CSS, like in the following example.
a,
ul {
font-weight: bold;
font-size: 14px;
color: grey;
}
.myClass {
font-weight: bold;
font-size: 14px;
color: grey;
}
is best ...
.myclass {
font-weight: bold;
font-size: 14px;
color: grey;
}
is even better (lower-case)
This way, the DOM engine will get to the element without having to stack across all a and all ul tags in your document.
