What is HTML ?
Whenever you are planning to build anything from scratch the first thing you will do is to well -structure it right? HTML does it when you are getting started to build web pages/websites. HTML is the markup that contains all the actual stuff that a web page has. All the text on this page you’re reading right now is inside HTML tags that tell the browser how to order the content on the page.
What is a HTML tag ?
The HTML tag is the combination of <> and tag-name.
// HTML tag :
<tagname>
// Opening tag :
<tagname>
// Closing tag :
</tagname>
There are two types of HTML tags :
- Opening tags
- Closing tags
The only difference between opening and closing tags is the forward slash after the opening bracket of a closing tag.
What are HTML Elements ?
A HTML element is the combination of the opening tag, some content and the closing tag.
// HTML Element :
<tagname> some content .. </tagname>
There are some elements that have no content and no closing tag. These elements are called Empty Elements.
//Example
<br>
The basic structure of HTML
<!DOCTYPE html>
<html>
<head>
<title>Page's Title</title>
<link ..... >
<script>......</script>
</head>
<body>
.
.
.
.
</body>
</html>
- The
<!DOCTYPE html>tag defines that this document is an HTML5 document. - The
<html>element is the root element of an HTML page. - The
<head>element contains meta information about the HTML page. - The
<title>element specifies a title for the HTML page (which is shown in the browser's title bar or in the page's tab) - The
<link>element is an empty element, it contains only attributes. It defines the relationship between the current document and an external resource. It is used to link to external style sheets. - The
<script>element either contains scripting statements or points to an external script file through the src attribute. - The
<body>element defines the document's body. It is a container that contains all the required tags and information that need to be displayed on the web page.
What are Inline and Block Elements ?
Every HTML element has a default display value. There are two types:
- Block
- Inline
Block Elements:
A block element always starts on a new line. It always takes up the full width available (i.e.) it stretches out to the left and right as far as it can.
Example: div, nav, heading tags etc.
Inline Elements:
An inline element does not start on a new line. It always takes as much as width it requires.
Example: button, span, input etc.
