I\'m looking to make the clickable area of links bigger than they actually are for accessibility since for the intended users it can be difficult to hit them. About 1.5x the siz
I am pretty sure you cannot do what you are asking. The only things that are coming to mind are adding padding, margin and line-height. While it isn't my favorite solution, but depending on the context of the site, maybe having a page with all the links listed, which has a bigger target.
Also, maybe use the outline
& the outline-offset
CSS properties with good contrast to let people know are on the link.
Another thing is, people who need a bigger target, use the keyboard more often to navigate a website, so making your site more keyboard friendly may help. For example, do you have a header and a sidebar, via code, does those come before the main content? If so placing a skip nav link, or a few (depending on layout), may also help.
