What is CSS?
The full form of CSS is Cascading Style Sheet. CSS is a simple design language. Which is designed to simplify the process of presenting web pages. You can control the color of web pages, font style, distance between paragraphs, etc. using css. That is to say. CSS makes the design of a web page attractive. We will talk about the rest of CSS in more detail below.
Now when it comes to CSS history, Hakon Wium Lee invented CSS on 10 October 1994. To mainten CSS, a group was created within the W3C named CSS working group. The task of this group was to create a specification document, this is the group that keeps updating the CSS. There are three main types of CSS working. Which are described below.
Types of css
There are basically three types of CSS.
- Inline Style Sheet.
With the help of this Style Sheet, inline style is used in web pages only where it is needed. You can use the inline style sheet to configure a particular html element. Inline css gives you the freedom to change any one element. Its specialty is that when we change one element, it does not change the other elements.
- Embedded or Internal style sheet.
These style sheets are used in the top (head section) of the pages. The internal style sheet is placed within the <style> element. This type of style sheet rule applies to all elements of the page. When we use the style element, the type attribute is also used in it. Here the type attribute specifies what type of style to include in the document.
- External Styel Sheet.
This is the most interesting Styel sheet of CSS. In this, we coding css in a separate file and save it with .css extension. Now whenever we connect CSS file with html file with the help of <link> element then this css file has effect on the whole html file. This is done when you want to change the design of a website one by one instead of changing it one by one.
So by now you must have known what CSS is in CSS. So let’s move on to this article and know why CSS is used.
Why CSS is used?
By now you must have known what CSS is, and it is used for designing a web page like – its page layout, text color, font and text style formatting. CSS is a very powerful style sheet language, from which we can control the look and feel of the written content. Suppose you have a website element (title). Now if we want to change the size, color of this title element and padding around it, then we will use CSS to change the appearance of this element here. You can easily understand why CSS is important for web designing by knowing the advantages of CSS.

What is the difference between HTML and CSS.
1) The first difference between HTML and CSS is that html delineates the content and structure of a web page. Rather css modifies the design and display of html element.
2) The second difference between these is CSS can be used in html files. But html cannot be used in css style sheets.
3) The third difference between HTML and CSS is that there is no method of using html elements. Rather, any method of Inline CSS code, internal and external stylesheet can be used to implement the codes of css.
4) The fourth difference between these tags is used in html. html tags are basically keywords (tag names) that are enclosed in angular brackets and usually come in pairs. Eg – opening tag
<tagname> closing tag </tagname>
Whereas CSS has selectors that represent code blocks. css codes are written within curly brackets {}. To define the styling of CSS CaCM code, we define them by properties and value. We put a colon: point between properties and value.
