HTML Definition | The Interactive Glossary

HTML uses a finite list of tags that describe the general structure of various kinds of documents linked together on the World Wide Web. Web browsers utilize these tags to interpret parts of the page. For instance, the tag <h1> indicates the start of a header, while </h1> signals the end of the header. Anything between those two tags will be displayed using predefined text style for headers.

HTML allows web developers to embed images and objects and create interactive forms on web pages. They can also embed scripts into HTML, providing additional features not inherent in HTML itself, such as JavaScript web applications.

Frequently Asked Questions

Is HTML only for webpages?

HTML can be used for many forms of electronic communication. For example, most email clients utilize HTML to allow formatting and embedded content within email, such as a branded design, photos, or video.

Can I create dynamic content with HTML?

HTML simply specifies the look of a webpage, directing a browser on how to display font, images, and other content. In order to create dynamic or interactive content, developers need to embed other scripting language, such as JavaScript or PHP, into their HTML code.

Do I have to know HTML to create a website?

There are plenty of programs available that will help you build a website without knowing a single word of HTML. The easiest programs are website creators, which are often offered for free with hosting plans. Most include dozens of pre-designed templates to start from, and you can drag and drop items using their easy-to-follow menu. You may be charged extra for more advanced features, but these are a great place to start. For a more feature-rich option, you could also install a content management system, such as WordPress. Like a website builder, you can choose from a large selection of modern-looking templates, but with a CMS you can do as much customizing as you want for free. Of course, knowing some HTML will give you the freedom to further customize your site, regardless of the tool you use to create it. But it’s not required.

How does HTML compare to CSS?

CSS, or Cascading Style Sheets, specifies the style of font and other features that are used within HTML documents. For instance, it is advisable to use a consistent set of fonts across your entire website, rather than varying them from page to page. You could include these style elements in every page you publish, or you can ensure all of your pages have the same look by creating a CSS file for your site. In the CSS, you specify the font for different styles of text, such as your headers and body text. Wherever you use a defined text element on your site, it will be referenced against the CSS file to ensure it always looks the same.
