Reply To: category dropdown width

one more quick question, for my learning process – if I wanted to change the width to only 2 of the 4 categories, but with the id’s in the same line, how would I write the code? This doesn’t work apparently –

#menu-item-9494 #menu-item-9526 .wd-dropdown-menu.wd-dropdown {
width: 255px;
}

maybe it’s not possible with them in the same line and have to write them in particular?
