not october, but you could make a script to switch the class of your for each theme, and then define the styling of each theme in your css ^_^
I'm not october either but you can use a special css doohickey called the :has() slector. You basically make a form where you check a box and then tell css that when that box is checked to use the variables defined below rather than the defaults!
okay!! thank u guys for helping :33 ill try them when i get back from school
i'm not lostlove but you can make your element not appear by default by using "display: none;" and then on the element you want to click put onclick="{document.getElementById('urelementid').style.display = 'block';}" :3
okay thank you!! ^^
