Customising list view

Hi,

I’m new to all this, so please be gentle.

In list view, I’m trying to change the font sizes and colours of pretty much all the dates, times and event titles, location and text, but am struggling to work out how to do it. Could someone point me in the right direction, please?

Also, is it possible to change the colour of the horizontal dividing line that’s between the calendar and the list of events below it, and add diving lines (with colour)between the date of the event on the left and the details of the event on the right?

Your help would be much appreciated.

Thank you.
