small e-commerce website

Small e-commerce website that works correctly on older computers. Newly created websites break-up on screen, freeze or crash on older computers. Old, very old e-commerce websites work just fine on old computer, new computer, cellphone, tablet, ANYTHING. Disregard the skills entered for this project. It is just another example of DUMB programming asking end user non-programmer to define required skills. God, today's programming really SUCKS. How dumb and illogical!!!
