jquery - Add class and change css dynamically (jquery)

Question

I'm working on a project where I'm parsing a json file to get the contents then do $.post using php to update changes. I'm able to read and write without any issues.

However, after I parse the data from json, I if I make any changes like adding a new class via click it adds the class but doesn't apply the css.

Ex:

    <div id="someID">lorem ipsum</div> <!-- (assuming I am "appending" this div via jquery and if I clicked on this div)

    <!-- it will become -->
    <div id="someID" class="red">lorem ipsum</div> <!-- the text and/or background should be red -->

I think I can apply a style="color: red" instead of applying class but I don't want that.

Any suggestions on how I can make this dynamic/live? Thanks.
