HTML Basics Tag

Introduction

The HTML tags are special keywords by which we can specify the format and appearance of any website. In HTML, the tags are bounded in < and >. All the tag starts with an open angular bracket(<) and ends with a closed angular bracket(>). Some of the tags end with a forward slash before the name of the tags. We can also place the HTML tags inside another tag.

Why do We Need to Open and Close HTML Tags?

It is very important that all the tags must be open and closed. It tells the web browser that when the piece of code begins and when the piece of code closes so that the browser can distinguish it from the other section of the webpage.

When we miss any one of the closings tag, then it can result in an incompatibility for the browser. It can also result in the improper appearance of the webpage. When the developer troubleshoots the HTML program, then it shows the missing closing tag.

Essential HTML Tags

Every HTML code has some essential tags. These are needed for the web browser to understand and display the webpage correctly. These also help the web browser to distinguish between normal text and HTML code. Four basic essential HTML tags are needed for the creation of the webpage. These are as follows.

  1. <html></html>
  2. <head></head>
  3. <title></title>
  4. <body></body>

Before talking about the above basic essential four tags, let's talk about the HTML document declaration, i.e., <!DOCTYPE>.

<!DOCTYPE>

In HTML, <!DOCTYPE> is not a tag; it is just an HTML document declaration. It shows the version of HTML that we are using in our program. All the HTML code must start with this declaration, and this is not case-sensitive.

Now let's discuss the main essential tags briefly.

1. <html></html>

With the help of this tag, we can define the document as a web page. We can also specify the beginning and end of HTML code with the help of these tags. All the tags of HTML are contained by this tag except <!doctype html>. All the tags of HTML are nested inside the <html></html> tags.

Syntax:

2. <head></head>

With the help of these tags, we can define the heading section of HTML code. It defines the information about the web browser, and this information is not displayed on the web page. It also contains all the information related to the web page. It also contains some tags like <title>, <meta>, <link>, etc.

We can locate the <head> tag in between the <html> tag and <body> tags.

Syntax:

3. <title></title>

We can provide the title for the webpage with the help of this tag. We can define the <title> tag inside the <head> tag. After giving the title for the webpage, the name of the webpage appears on the tab or title bar in the browser window.

Syntax:

4. <body></body>

With the help of this tag, we can declare all the information and other visible content for the webpage. The <body> tags contain all the information like images, links, plain text, videos, etc. We can declare all other tags like <p> tag for paragraph, <strong> tag for bold text, <a> tag for images, <ol> tag for the ordered list, etc.

There are six heading tags available on the webpage. These tags are h1, h2, h3, h4, h5, h6. The <h1> tags show the most important and most priority heading tag, and <h6> has the least priority.
