Just wana confirm if this css code is valid?

ul.approve-icons, li.approve-icon
width:IMG_ICON_POST_APPROVE_WIDTHpx;
levels:IMG_ICON_POST_APPROVE_HEIGHTpx;

i highly recommend you note area placement and rule truth.

thanks

ul.approve-icons, li.approve-icon
width:IMG_ICON_POST_APPROVE_WIDTHpx;
levels:IMG_ICON_POST_APPROVE_HEIGHTpx;

If similar to this is what you necessarily mean then it’s correct.

ul.approve-icons, li.approve-icon
width:100px;
levels:100px;

No, not necessarily correct.

Try making the next change:
through:
px;

to be able to:
px;
