And, idk about you guys, but for me it's super distracting. I was getting a bit sick of all the text on the page anyway, so here you go. A new code tester based on their code (because I'm lazy lmao), with a clean, un-distracting page layout.
Just like DRAAC's, my code tester is good for HTML codes, div styled codes, and full HTML/CSS pages (but not CSS alone). Oh and, even after previewing, CTRL+Z still works, which is always a big bonus for me.
