How do I change the size of 2 <td>s in my table?

[array0024826768]

Hi, i’ve started learning HTML and CSS this week. Along side the course on here im trying a little project to make a football scores page. I want to give the 2 yellow s in the middle columns slightly more width but i’ve got stuck. I did it with padding but then i couldn’t change their color. Any feedback would be nice please.
