I was just trying to add a simple font-resizer jQuery script to a WordPress theme.
This example seemed really simple but it just won’t work.
After a while, I stumbled on this page in WordPress Codex where it suggested replacing the jQuery shorthand – $ symbol with the word jQuery.
For eg:
$(document).ready(function () {
became
jQuery(document).ready(function () {
So, once I replaced all the ‘$’ symbol to jQuery, it worked flawlessly!
If your jQuery script is not working on your WordPress theme, make sure you check this.
