BRUH WHY DOES HTML HATE ME

EVERYTIME I WANNA PUT A GIF THAT GOES OVER THE WHOLE PROFILE OR LIKE IS SET IN ONE SPOT OUTSIDE A SECTION BOUNDARIES IT FUCKS UP. IF ANYONE KNOWS HOW TO FIX THIS PLEASE COMMENT. PRIME EXAMPLE IS THE LPS CAT AT THE BOTTOM, SHES MEANT TO SIT ON THE LEFT OF THE SCREEN AND STAY PRESENT WHEN YOU SCROLL. JUST SHOOT ME.
