Subheading on each category page of the shop / underline each category

Hello,

I would love to be able to add a subheading to each page on my shop. They are currently organised by categories, but there isn’t an option to add a title or heading to describe what page they are on.

I would also love to add an animated underline beneath each category title to show which page is active, is this possible?

And lastly, the social icons in the footer aren’t editable, I wanted to make them the same navy blue colour that I have on the rest of my website but I can’t seem to be able to edit them, please let me know if this is possible too?

Thank you so much for your help in advance!

Chloe
