Here is some SCSS code I am working with:
.a {
height: 100px;
width: 100px;
}
.b {
@extend .a;
height: 200px;
}
After compiling, the CSS appears as follows:
.a, .b {
height: 100px;
width: 100px;
}
.b {
height: 200px;
}
When applying this style to a <div class="a b">, the height remains at 100px instead of 200px. How can I get the CSS to recognize and implement the height of 200px in this scenario?
Which CSS selector will take precedence in the following scenarios, as a general rule for any CSS file?
The height will be set to 200px for <div class="a b">.
.a {
height: 100px;
width: 100px;
}
.b {
@extend .a;
height: 200px;
}
The height will be set to 100px for <div class="a b">.
.b {
@extend .a;
height: 200px;
}
.a {
height: 100px;
width: 100px;
}
The height will always be set to 200px for <div class="a b">, regardless of order.
.a {
height: 100px;
width: 100px;
&.b {
height: 200px;
}
}
This feature already operates in the exact manner you desire.
Ensure that the .b class is placed above your .a, .b, as the most recent style declared will take precedence.

Finally, prioritize based on the sequence of declarations: when two statements possess equal priority, origin, and specificity, the latter one mentioned prevails. Declarations within imported style sheets are deemed superior to those in the style sheet itself.
.a, .b {
height: 100px;
width: 100px;
}
.b {
height: 200px;
}
/* ignore */
div{
background-color: red;
}
body{
display: inline-flex;
}<div class="a"></div>
<span>|</span>
<div class="b"></div>
<span>|</span>
<div class="a b"></div>If I understand your question correctly, it can't be overwritten in the same way
.x, .y {
height: 150px;
width: 300px;
}
Because this will assign width: 300px; to both .x and .y, but if you want to assign width: 300px; to only .y, then the code you already provided does that perfectly.
One option is to utilize a wrapper element
.a {
height: 100px;
width: 100px;
}
.b {
@extend .a;
}
.wrapper .b {
height: 200px;
}
For the HTML structure, you can nest the elements as follows:
<div class='wrapper'><div class='b'> XXX </div></div>
To ensure specific styling takes precedence, consider using !important.
.a {
height: 100px;
width: 100px;
}
.b {
@extend .a;
height: 200px !important;
}
