What is HTML element?
An HTML element is a building block of an HTML document. It is a collection of tags, attributes, and content that describe a specific type of content on a web page.
Elements are defined by tags, which are enclosed in angle brackets (< and >). For example, the paragraph element is defined by the <p> tag. Elements can also have attributes, which provide additional information about the element. For example, the <img> element has a “src” attribute that specifies the URL of the image.
HTML elements can be nested inside other elements, creating a hierarchical structure for the document. For example, a heading element (<h1>) could be nested inside a div element (<div>) which could be nested inside a body element (<body>).
The most common type of elements are the block-level elements and inline elements. Block-level elements take up the full width of the available space, and create a new block formatting context. Some examples of block-level elements are <div>, <p>, <h1>-<h6>, <ol>, <ul>, <li> and <table>. Inline elements take up only as much width as necessary, and they do not create a new block formatting context. Some examples of inline elements are <span>, <a>, <img>, <strong> and <em>.
In short, HTML elements are the building blocks of an HTML document, they are defined by tags, have attributes and they create the structure of the webpage.
The syntax of an HTML element is made up of the following parts:
The opening tag: This is the starting point of the element, and is defined by the element name enclosed in angle brackets. For example, the opening tag for a paragraph element is <p>.
The content: This is the text or other elements that are contained within the element. For example, the content of a paragraph element might be “This is some text in a paragraph.”
The closing tag: This is the end point of the element, and is defined by the element name enclosed in angle brackets, preceded by a forward slash. For example, the closing tag for a paragraph element is </p>.
The syntax of an HTML element would look like this:
For example, the syntax of a paragraph element would be:
<p>This is some text in a paragraph.</p>
Note that some elements do not have a closing tag, and these are called void elements. For example, <img> and <input> are void elements. The syntax for void element would look like this:
For example, an image element would be:
<img src="image.jpg" alt="image">
