The caption on top of the collection's cover page photo under "Shop by collections." Is that a part of the photo or written out in code? If it's written out and not part of the photo, the size should be 2em with same shadow properties as other text with shadow properties.

Its the name of the collection, so it coming from code. Fixed size and added shadow.

Just making sure the spacing around the "Shop by collection," underline and the space between underline and content is 24px (see attachment).

This was 30px, same as the gap between the photos earlier. I have changed this to 24px now.

Also the spacing before and after "Lorem ipsum dolor sit amet. A…" is the same as above: 48px or 3em

Correct.

You mentioned that search is still possible. Not sure the priority of this but you can use the mock up above for reference for where it will be. More mock ups soon. I imagine this is pretty low-priority, as in doesn't need to be finished for launch.

Let us have a separate task for this - T78379
