The CSS3 selector matching a value starting with "[attribute^=value]" does not match a value that has spaces after the quotation marks

When using the

div[class^="test"]

selector, keep in mind that it will not select an element with a class attribute like

class="  test-something"

(This selector was generated on the backend.)

Using the

div[class^="  test"]

is not a valid choice.

Do you have any suggestions for this issue?

Answer №1

Explaining the use of ^=:

It signifies 'begins with..'

div[class^="test"] { }

This would be effective on an element like:

<div class="test and-some-class"></div>  
<!-- only if the very first word in your class matches "test" -->
<!-- hence, class=" test something-else" won't match


To target with the CSS Selector:

It indicates 'contains..'

div[class*="test"] { }

This will be effective on

<div class="class test something-else"></div> 
<!-- class name can be anything. "test" might appear anywhere within it -->
