Hi I'm a beginner too! This group can be really useful for this stuff, especially the image at the top which gives all of the IDs which is what you're looking for :) I've been messing around with the CSS a bit and I'm starting to get the hang of it.
You'll want something like this:
.profile .table-section heading {
/* heading stuff here or remove it entirely like I did with display: none; */
}
.profile .table-section {
/* background/outside stuff - margins, background behind all of the table, etc */
}
.profile .details-table td:(first/last)-child {
/* the specific cells in the interests table - you can change margins/background/etc here. First is the first column and last is the second one */
}
.profile .details-table td:(first/last)-child p {
/* text formatting so font and text colours and stuff */
}
I hope this helps!
