Learning about the web front end, browsers and editors are our friends so it’s important to know a little bit about browsers such as: What are the major browsers
Major browsers
Mainstream browsers have a certain market share and have their own independent development of the browser kernel can also be called the native browser, which we commonly have: IE/Edge, Chrome, Safari, Opera, Firefox and the qq browser, uc browser that we all use a lot are shell browsers that just take the core of the native browser, simplify it, wrap it up,
