How to make jQuery $ (element) .css () effects permanent?

Question

For example, when using the font-size / button switch, if I use

    $('#container p').css('font-size', '24px');

it works as expected, but if I add paragraph elements to the container later (via ajax, etc.), they will not be in the style of the updated font size. I know that this is the intended behavior of the method .css(). I'm just asking:

What is the correct style change approach for the CSS selector and the persistence of these styles?

Answer 1

That's right, well, when you execute this command, it pushes all the pelements in #container. If you want it to be permanent, you could create an element <style />and add CSS styles there.

If you enter through AJAX a replacement for #container, then all content will be destroyed and replaced with new content. All tags <p>that you added, the style will no longer exist, and it will need to be repeated in a new entry.

That you could try creating a class definition on the fly .
