HTML stands for Hyper Text Markup Language.
HTML uses angular brackets for the markup tags. These tags tell the computer how to display the content. Content is different from appearance.
CSS is used in tandem with HTML to control the style of the content.
HTML files are commonly saved with .html extension. Sometimes you will see them saved as .htm, but not as often.
The world’s first web page was written in HTML. You can see how straightforward the content is displayed. Everything you see is the default structure used by HTML, i.e., the size of the headings, the blue links. There is no styling to change the appearance, and there is no interactivity to the page. It is strictly HTML.
HTML5 is the latest industry standard for editing in HTML.
Get a Free Text Editor
You need a text editor to write HTML.
Here are some popular choices:
If you have Mac you can download TextWrangler.
Do not use word processing software such as Microsoft Word or Google Docs for writing HTML. It causes extra formatting to be put into your code, and you will end up using a text editor to get rid of it. So it’s best to choose from one of the simple text editors described above.
It’s also important to note that while HTML5 is intended to be cross browser compatible, you should still check your pages to see how they will look in other browsers. For example, you might use the popular Chrome, but someone else might use Mozilla. Always check how your page will look in different browsers. Do not expect uniformity.
Knowing how to code well in the latest version of HTML is a web development skill that any good developer should know.
