When programming in any language, it is important to understand the different data types available. In HTML, these data types are known as core data types. Core data types are the building blocks of any program and allow developers to store, manipulate, and display different kinds of information.
Text Data Types:
One of the most common core data types in HTML is text. Text data types are used to represent and display alphanumeric characters.
They can include letters, numbers, symbols, and whitespace. Text can be styled using various tags such as underline, bold, and italic.
Numeric Data Types:
Numeric data types are used to represent numbers in HTML. There are two main numeric data types: integer and floating-point. Integers are whole numbers without any decimal points, while floating-point numbers include decimal places.
Integer:
Integers can be positive or negative whole numbers or zero. They are often used for counting or representing quantities that cannot have decimal places. Examples of integers include 1, -5, and 1000.
Floating-Point:
Floating-point numbers can have decimal places. They are used when accuracy is required in calculations or when representing values that can be fractions. Examples of floating-point numbers include 3.14, -0.5, and 2.71828.
Boolean Data Type:
The boolean data type is a core data type that represents only two possible values: true or false. Booleans are often used in conditional statements and logical operations where a decision needs to be made based on a condition’s truthiness.
Lists:
HTML provides tags for creating ordered and unordered lists. The unordered list (
- ) tag is used to create a bullet-pointed list, while the ordered list (
- Item 1
- Item 2
- Item 3
- First item
- Second item
- Third item
- ) tag is used to create a numbered list.
Unordered List:

Conclusion:
Understanding core data types is essential for any HTML developer. Text, numeric, boolean, and lists are the fundamental data types that allow for the creation and manipulation of information within an HTML program. By utilizing these core data types effectively, developers can build powerful and dynamic web applications.
