Selecting an element based on its class using CSS

Is there a way to select all td elements within a tr that has the class my-class?

I attempted

tr .my-class td

Furthermore, is it preferable to fully qualify selectors?

Would using table tbody tr td be more effective than just td?

Answer №1

It is always best to minimize the amount of selectors you use in CSS. Instead of writing

tr.my-class td

You can simply write

.my-class td

Your second question is closely related to the first one. When you have a selector like

table tbody tr td

Your browser has to go through all the td elements, then check which ones are within a tr, followed by tbody, and lastly table. Since td elements are always contained within tables in well-structured code, there's no need to over-specify your selectors.

Answer №2

If you need a quick solution, try utilizing this code snippet:

.example-class th

Avoid over-qualifying your selectors as it can lead to unnecessary specificity issues. Check out more about this concept here

Answer №3

One way to approach this is:

.custom-class td {
    // add your css styles here
}

Alternatively...

tr.custom-class td {
    // insert your css styles here
}

Another option is...

table tbody tr.custom-class td {
    // include your css styles here
}

It all depends on how specific you want to get.

I suggest keeping your css code minimal as long as it achieves the desired result.
