HTML (Hypertext Markup Language) is the backbone of every web page you visit. It provides the structure and content of a web page, making it essential for any aspiring web developer to understand. One of the most fundamental parts of HTML is the use of tags.
What is an HTML tag?
An HTML tag is a piece of code that defines an element on a web page. Elements can range from headings and paragraphs to images and links. Tags are surrounded by angle brackets (

Many HTML tags support attributes, which provide additional information about the element. Attributes are included within the opening tag and have a name-value pair structure, like this:
For example, the
<a> tag uses the
href attribute to specify the target URL, while the
<img> tag uses
src for the image source and
alt for the alternative description.
Semantic HTML is the practice of using tags that convey the meaning and purpose of the content they enclose. It improves the readability of the code and the accessibility of the web page. Some examples of semantic tags include
