css having a range after a class attribute - css

Question

I have three class : product1, product2, product3. I can add css to all these class as follows:
.product1, .product2, .product3{
// add css here
}
But I am looking for more cleaner code to track 1 to 3 followed by 'product' and add css to these. My expectation can be Pseudocode Examples:
.product1to3{
// fun with css.
}
Is there any approach in css?

Answer 1

There is no such kind of css pseudo on what you wanted to achieve.
You can try to use SASS to achieve what you wanted.
and then use the #for Directive
SASS
#for $i from 1 through 3 {
.product#{$i} { width: 20px; }
}
CSS
.product1 {
width: 20px;
}
.product2 {
width: 20px;
}
.product3 {
width: 20px;
}
Also you can try to use LESS
Hope this helps

Answer 2

pure css implementation JSfiddle
So basically you need an "Attribute Begins With Selector" i.e select all classes which start with "product" and then you can use nth child attribute to select range
div[class^="product"]:nth-child(n+4):nth-child(-n+5) {
background: red;
}
Really good article on complex css and nth:child

Answer 3

/* This selects all the elements which have the class name starting with
"product"
*/
[class ^= "product"] {
//CSS
}

Answer 4

If you have an unknown / high number of ".product(x)", and for whatever reason don't want to use an extra class to target them, you can get away with an attribute selector that matches all elements that have a class containing "product".
[class*="product"]
div{
border:2px solid tan;
height:40px;
}
[class*="product"]{
background:steelblue;
}
<div class="product1"> product 1 </div>
<div class="product2"> product 2 </div>
<div class="not"> not a product</div>
<div class="product3"> product 3 </div>
<div class="product4"> product 4 </div>
It occupies just 1 line of compiled CSS, so it's minimal footprint, but be careful how you apply it.

Answer 5

Not an answer for the OP but for others that may find their way here remember that you can use multiple classes for each element.
html
<div class="product product1"></div>
<div class="product product2"></div>
<div class="product product3"></div>
css
/* shared styling */
.product {
display: flex;
background-color: gray;
border: 1px solid red;
}
/* individual styling */
.product1 {
color: black;
}
.product2 {
color: white;
}
.product3 {
color: blue;
}
