javascript - How to add ::before pseudo element on elements created dynamically by jQuery -

I am dynamically creating some elements with jquery (id test_element1 , Test_element2 and so on ..)

I have CSS below -

  div {id ^ = test_]: first {content: ""; Height: 100%; Width: 100%; Box-Shadow: #aaaaaa 0px 0px 10px inset; Status: Completed; Left: 0 pixels; Top: 0 pixels; Z-index: -1; }  

The :: first element is not visible when viewing the element. It only shows when already has my HTML (i.e. static content) ) Contains test_element1 .

How do I :: first appear for my dynamic elements?

The answer is that

you can not manipulate pseudo elements such as: after And: You can not even add dynamically before using javascript or jquery.
