i feel like a poser bc i dont know much html/css..

literally the only thing i can remember is how to put in an image like all i know how to do off the top of my head is input images. like. ok. how to be useless 101. AND I DONT EVEN KNOW HOW TO SIZE THEM DOWN!!!

LIKE. HE'S SO LARGE. HOW DO I SIZE IMAGES DOWN??? THSI IS PATHETIC!!!!

 i'm gonna be honest, i take pre-made code and js change the colors/pictures of stuff... tell me im not the only one... my brain explodes when i try to remember all the stuff i try to learn abt css, and i dont know much sources that teach it. like, i know w3 schools, but that website gives me a brain aneurysm trying to actually REMEMBER what i read. i'm NOT freaking futaba sakura dude... i dont know how to do this...

this is a showcase of my pathetic newgen brain. if u guys are pros are css/html or u at least know some, how did u learn?
