HTML, or HyperText Markup Language, is the standard markup language used to create web pages. HTML allows web designers and developers to structure and format the content of a web page using tags. In this article, we'll take a closer look at HTML tags, including what they are, how they work, and some of the most commonly used tags.
What are HTML tags?
HTML tags are elements that are used to structure and format content on a web page. They are surrounded by angle brackets, < >, and are usually composed of a tag name and attributes. For example, the <h1> tag is used to define a heading, and the attribute "class" can be used to assign a class to the heading.
How do HTML tags work?
HTML tags are used to define different parts of a web page, such as headings, paragraphs, links, images, and tables. The browser reads the HTML code and uses the tags to display the content of the web page. The browser knows how to interpret the tags based on the HTML specification, which defines the meaning and behavior of each tag.
HTML tags can also be used to add attributes to elements. Attributes provide additional information about an element, such as its size, color, or alignment. For example, the <img> tag is used to display an image, and the "src" attribute is used to specify the URL of the image file.
