HTML is the computer language that your website is written in, under the covers. When you are editing your website, the tool that you are using converts your changes into HTML, and stores that. When someone visits your page, it is the HTML that gets sent to their web browser.
Their browser then understands the HTML and converts it back into something that makes sense to normal people. But before all the clever tools that people have now for editing their websites, people had to write the HTML themselves. And it turns out that people aren't very good at writing HTML perfectly.
They tend to make mistakes some people a lot more than others. So, the companies that developed the early web browsers decided to try to accommodate some of the common mistakes.
To try to work out what they really meant, instead of the glaring error that they actually wrote. This was good because it meant that less technically competent people could attempt to write HTML without it being too strict and the website would still look right.
But it also meant that people could be sloppy, so it effectively encouraged sloppiness. Something else that the web browser developers wanted to do was to make their browser better than the others. So they decided to add new features to HTML that the other browsers didn't support. For example, the early Netscape browser introduced the ability to "blink" text and images so that they flashed and the early Microsoft Internet Explorer added the ability to scroll text and images across the page.
If you used these extra HTML features, your website would effectively only work properly in one browser. Anything outside of this standard might still work, but it would be unofficial and you use it at your own risk.
All of that makes it a lot easier if you have reasonable HTML. Matt Southern has been the lead news writer at Search Engine Journal since With a degree in communications, Matt Web Development.
