Building Blocks of HTML

Last time we have seen, Semantic Elements in HTML. Now we are going to learn about the Building Blocks of HTML. So let's get started...

What are Building Blocks?

The Building Block is nothing but a group of different types of elements that are used to implement a program. It includes sequential layouts, selections, and iterations which create the algorithm to implement a program.

In HTML, there are mainly two Building Blocks which are Tags and Attributes. The Comment is also one of the HTML Building Blocks, but mostly it is not considered as the Building Block.

Tags in HTML

In HTML, all the Web page development code is written in between the opening and closing tags of HTML. Each Tag in HTML represents its own meaning itself, to the user or developer.

These tags are enclosed between the opening and closing angular Brackets (<Tag_Name>). The HTML Tags are always closed using the slash symbol after the opening angular bracket (</Tag_Name>).

Syntax : 

<tag_name> Web-page Content </tag_name>

Attributes in HTML

The Attribute of HTML is used to provide extra information about the given tag. These attributes are used in the start Tag of HTML.

The HTML Attributes mainly consist of Attribute names and Attribute Values.

Syntax : 

<tag_name attribute_name="attribute_value"> Web-page Content </tag_name>

Comments in HTML

The comments help us to understand the written program very easily. The comments are mostly used by the developers to understand the meaning and flow of the program.

In HTML, there are no single-line or multi-line comments. The comments can be given using the opening angular bracket(<) later on the exclamatory mark(!) followed by two hyphens(--). And the comments are closed using the two hyphens (--) followed by the closing angular bracket.

Syntax : 

<p> I am the Paragraph...!!!</p>    <!-- Comments -->

Basic Attributes in HTML

As we have seen in the above Building Blocks, there are attributes that are used to provide extra information about the given tag. In HTML, there are two main attributes that are mostly used in the programs. Let's take a look at them...

1. class=" "
2. id=" "

The above two attribute defines the unique class name and id for the specific tag. These attributes are mostly used for designing the web page using CSS.

The HTML Elements can be accessed in CSS or any other language using the class and id attributes of HTML Attributes.
