Move List to Left Margin

Hello, is it possible to move the list (table of contents) flush with the left margin? On mobile it indents and puts it in the middle of the page so it looks awkward.  For example, see this post here: https://iglobal.net/2021/07/20/st-kitts-tax-residency/ scroll down the page and you will see the list. For mobile, I want it to be against the left margin or at least closer to it. It is too far across the page. Can you assist? Also, your website is moving extremely slow, it takes one or two minutes for each page to down load. Follow up replies by email is also not functioning, it has been like this for over a year. Thank you - Edwin
