Websites would look boring without CSS as this styling language is responsible for text style, size, color, and positioning on a web page.

What Is CSS?

Cascading Style Sheets, abbreviated as CSS, is a language that describes how HTML elements should be displayed on a screen or paper. CSS was created by World Wide Web Consortium (W3C) in 1996.

HTML elements were not designed to have tags that could help format a web page, and developers were only required to write a markup for the page. The introduction of tags such as <font> when HTML 3.2 was launched introduced new problems for developers. 

As web pages have colored backgrounds, different fonts, and multiple styles, rewriting code became expensive and painful. W3C schools introduced CSS to solve these challenges, and it has continued to evolve over the years.  

Why CSS?

#1. CSS is Efficient

CSS saves us from the pain of adding tags like font, element alignments, border, color, background style, and size on every web page. 

#2. Save Time

You can easily change the entire website’s appearance by altering the external CSS file. 

#3. Multiple Device Compatibility

Modern web users access sites on gadgets with varying screen sizes, such as PCs, tablets, and smartphones. CSS makes it easy to create web pages responsive to screen sizes. 

#4. Easy to Maintain Applications

Modern web applications are always evolving. CSS makes it easy to change single components or even the entire website without altering the codebase. 

How Is CSS Used With HTML to Create Websites?

HTML is a standard markup language used for web page creation. On the other hand, CSS describes how web pages (created using HTML) are displayed. A web page created using HTML, and CSS will ideally have an HTML file of text, image links, and HTML tags

This HTML file can have either a separate CSS file linked to it using a link tag or employ internal or inline CSS styles. An HTML file can have a heading such as <h1> and a paragraph denoted by <p>. You can use CSS to instruct the browser to display all the content in the paragraph in bold or even make the header content 50 pixels and green in color. 

We will demonstrate how HTML and CSS work in the next section. 

Types of CSS

#1. External CSS

For CSS to be classified as external, there should be an HTML file and a separate CSS file with a .css extension. For example, style.css. The CSS file is linked with the HTML file/document using a link tag. 

Example of an external CSS file:

.main {

    text-align:center;   

}

.GF {

    color:red;

    font-size:50px;

    font-weight:bold;

}

#TP {

    color:blueviolet

    font-style:bold;

    font-size:20px;

}

The CSS file can be linked with the following HTML document:

<!DOCTYPE html>

<html>

    <head>

        <link rel="stylesheet" href="style.css"/>

    </head>

    <body>

        <div class = "main">

            <div class ="GF">Geek Flare!!!! </div>

            <div id ="TP">

               Your favourite tech portal

            </div>

        </div>

    </body>

</html>

The link tag links the external style sheet with the HTML document, while the href attribute specifies the external style sheet’s location. 

The final web page will appear as follows:

geekflare

External CSS is the most-recommended approach as it makes it easy to create reusable components and make universal changes to the codebase. 

#2. Internal CSS

Internal CSS is ideal when you have a single HTML document you want to style uniquely. The style rule set is written on the HTML document within the head section. 

This is an example of internal CSS:

<!DOCTYPE html>

<html>

    <head>

        <title>Internal CSS Example</title>

        <style>

            .main {

                text-align:center; 

            }

            .GF {

                color:Red;

                font-size:70px;

            }

            .custom {

                font-style:bold;

                font-size:20px;

            }

        </style>

    </head>

    <body>

        <div class = "main">

            <div class ="GF">Internal CSS Demonstration</div>

            <div class ="custom">

                The Results

            </div>

        </div>

    </body>

</html>

The rendered web page will appear as follows:

output

Internal CSS is not ideal in most cases as it makes the code in an HTML document so large, affecting the loading speed. 

#3. Inline CSS

Inline CSS contains the CSS style within the body. For instance, you can style a paragraph, a heading, or even a div using inline CSS. 

<!DOCTYPE html>

<html>

    <head>

        <title>Inline CSS</title>

    </head>

    <body>

        <p style = "color:red; font-size:50px;

                font-style:bold; text-align:center;">

            Inline CSS Demonstration

        </p>

    </body>

</html>

The rendered document will appear as follows:

inline-1-1

Inline CSS is not ideal if you want to scale your web application, as adding a CSS property to every HTML tag takes time.
