What is the name of a bright sunflower yellow spider about an inch big?

Some Jumping Spiders and Crab Spiders are yellow with some red and white markings at the back. They are small, the biggest one I seen was 0.5cm-1.5cm long. I never seen a crab spider before but I bet they are the same size. If they are going to fight, the jumping spider would have 90% chance of winning and crab spider would have 30% chance as the jumping spider has more stealth, its more cunning, more distance in sight and can jump 20-50 body lengths away. Oh and by the way the jumping spider is cuter (;
