WHY IS THIS SO HARD

SOMEONE TELL ME WHY CUSTOMIZING MY BLOGS IS SO HARD BROTHAA

LIKE AM I GENUINELY JUST STUPID OR SOMETHING WHEN IT COMES TO ALL THIS BEEP BOOP NONSENSE

'Chat gpt... Can you write a code to customize a spacehey blog...' THATS GONNA BE ME AT THIS RATE

IM GOING TO TURN INTO A SECONDHAND-THINKER TO CHATGPT

All I've been able to figure out, is how to change my background, and customize things like fonts and a few colors. THATS IT.
