Safari, the default web browser on Mac, gives you the ability to shrink or enlarge both the content and the text on all websites or just specific ones.
In Safari, you may be familiar with increasing or decreasing the font size on a website-to-website basis using the Command+Plus (“+”) and Command+Minus (“-“) keyboard shortcuts. But if you don’t want to fiddle with those settings for every site, Safari allows you to increase the minimum font size and have it apply to all the websites you visit.
