Main Difference

The main difference between HTML and CSS is that HTML is a “standard markup language” that describes the content and structural layout of a website whereas CSS is the presentation layer that defines how HTML elements are going to be displayed on-screen or in different media.

HTML vs. CSS

HTML stands for “HyperText-Markup-Language.” CSS stands for “Cascading Style Sheets.” HTML gives structure to the site through tags, elements, and attributes. Cascading Style Sheets (CSS) indicate how your website will be displayed. HTML allows us to incorporate pictures, text, videos, forms, and other content together into a cohesive webpage. Without CSS, your website would look rather boring and dull.

HTML is used to create the content of the page, such as written text. You can also rewrite words, resize images, and also add links to the text. CSS determines font size, font type, font color, page layout, styling around images, mouse hover effect, and more. HTML indicates the content and structure of the webpage. CSS is responsible for designing and styling websites that include: layouts, visual effects, background color, etc.

Anything that you can read or view on websites is being presented to you by a browser with HTML. CSS modifies, design and display HTML elements. HTML is easy to learn and code even for beginners. CSS is easy to maintain. For HTML, there are no defined methods. CSS consists of three style sheet methods: inline, internal, and external. HTML and CSS both are available offline and free to use.

What is HTML?

HTML is a standard markup language to create static web pages, also known as flat or stationary web pages. It is easy to learn. It describes the structure of web pages. Its elements tell the browser how to display the content. Its elements are represented by tags, which include headings, paragraphs, tables, etc. For HTML syntax tags are used. The browser only displays content written inside the HTML tags. The tag contains special characters such as starting tag ‘<,’ closing tag ‘>’ and a forward slash ‘/.’

Syntax

<tag>content</tag>

HTML consists of tags surrounding the content.
Tags are known as HTML elements that are used to describe a specific section on a webpage.
Text, links, images, and other information displayed on a web page are known as content.

Example

<!DOCTYPE html> <html> <head> <title>This is page Title</title> </head> <body> <h1>This is First Heading</h1> <p>This is paragraph</p> </body> </html>

What is CSS?

CSS stands for “Cascading Style Sheets,” which creates dynamic web pages and display different information at a different point in time. CSS describes how elements of HTML will be displayed on-screen or in other media. It saves a lot of work. You can control the layout of multiple web pages by a single style sheet all at once.

Syntax

selector { property: value; }

CSS consists of selectors that are succeeded by a declaration block.
Selector indicates which HTML element you want to style.
The declaration includes property and value separated by a colon, whereas a semicolon separates each declaration. The curly braces enclosing all declarations are known as declaration blocks.
Property signifies the aspects of elements you want to change.
The value specifies the settings you want to apply in the chosen property.

Example

h1 {color: red; font-size: 10px;} p {color: green; font-weight: bold;}

Types

Inline CSS: An inline style(inside an HTML element) can be written within a line to apply a unique style for a single element. e.g.,
```
<h1 >This is first heading</h1>
```
Internal CSS: An internal style sheet used for a single page having a unique style. Internal CSS has written within an HTML document in the head portion. e.g.,
```
<head> <style> body {background-color: skyblue;} h1 {color: red; margin-left: 10px;} </style> </head>
```
External CSS: An external style sheet can change an entire website by changing one file. Each page must have a reference to the external style sheet file within the <link> element inside <head> section of an HTML page. e.g.,
```
<head> <link rel="stylesheet" type="css/text" href="styling.css"> </head>
```
