World Wide Web is a subgroup of the Internet that involves websites and webpages that users can access via a web browser. Since all sites and pages are text documents, they need to be written in descriptive language that specifies the page structure. This language is called HTML (hypertext markup language).
HTML makes the page only readable without explicit styling. To control exactly how HTML elements look in the browser using whatever design you want. This is where CSS (Cascading Style Sheet) comes in.
What is CSS (Cascading Style Sheet)?
CSS is a style sheet language used for formatting content in HTML web pages. So it’s important to remember that CSS is not a programming language. Cascading style sheet is a design language that makes a website look more appealing than just pieces of text.
This is a design tool that often is combined with HTML or XHTML markup languages and requires creativity.
Where can we use CSS?
With CSS you can change the appearance and formatting of text, tables, and other elements separately from the content itself.
Cascading Style Sheet can be used to change the color and size of headings and links and even to create effects such as animation.
Based on where the CSS is added in the HTML document there are three types: Internal, External, and Inline. So in order to know which one is best to style our web pages with, we need to tell them apart.
What are the types of CSS?
Internal CSS (Cascading Style Sheet)
Internal CSS is also called embedded CSS. This type of cascading sheet is when the CSS code is inserted in the <head> section of the HTML document. This defines the style for a single page. This CSS style will be reloaded every time the website is refreshed. For example, you can use an internal style to assign colors to paragraphs on your page.
External CSS (Cascading Style Sheet)
With this type, everything is done externally on a .css file. This means you can do all the styling on a separate file, called a stylesheet. Then you have to create a link to this CSS stylesheet and put it in the <head> section of your document. You can apply the CSS to any page that you want. This helps you define the style for many HTML pages. As a result, by manipulating only one file you can change the whole look of the website.
Inline style (Cascading Style Sheet)
This style works with specific elements that have the <style> tag. So we can apply a unique style to a single HTML element. This makes it unfit for use on large-scale projects. In this case, we’ll have to search in HTML code to pick out where we’ve used inline styling.
Using CSS improves the page speed and the user experience.
CSS is a rule-based language. This allows you to use one CSS rule and apply it to all appearances of a certain tag within the HTML document. Which improves site speed. Also, it’s easy to improve user experience as CSS allows user-friendly formatting. You can apply specific formatting rules and styles to multiply pages with one string of code.
