How can I make final adjustments to the Dawn theme?

Hi,

I have almost finished my store and would like to make a couple of modifications:

  1. Make the headline on desktop in the main top image banner bold or slightly larger to be more impactful

  2. Move the text in the headline and subheading on desktop very slightly higher so it doesn’t interfere with part of my image behind it

  3. In the product section on the main page (desktop and mobile), I’m using a colour background and would like the font to be white in this section only

Is this possible, and if so how (without causing other probs).

Thanks very much,

Stephen
