Createa button- pixel size


I am dealing with this: when i enter div height: 50px, i get the answer:"Oops, try again.
Did you remember to give your div a height of 50px? It looks like it's 49.76666px.". What do i have to do????


set your browser zoom to 100% (ctrl 0) if that doesn't work, either find the zoom in the browser settings, or zoom in with ctrl + or zoom out with ctrl -
