What is CSS

The full form of CSS is Cascading Style Sheets. It is a type of language through which we design our website.

In simple words, CSS tells your browser what will be the font, color, size, position etc. of the contents (like text, image, paragraph etc.) available in the web page.

Learning CSS is very easy. We have created a complete CSS tutorial in Hindi for you. By reading and practicing it, you can easily learn to create an attractive website.

Keep in mind that nothing can be created with CSS without HTML, so it’s important to have knowledge of HTML.

HTML and CSS together provide the look and feel of a web page.

HTML gives shape to a web page, while CSS’s job is to make it attractive.

What’s the difference between HTML and CSS

You might be wondering why we should use CSS when we can create designs and change colors, sizes, and more in HTML? Wouldn’t HTML alone be enough? What’s the difference between HTML and CSS?

Let’s try to understand this with this picture:

Let’s now understand in simple terms how CSS differs from HTML:

HTML = Content; meaning we use HTML to add only content to our pages. Here, content means: text, headings, paragraphs, images, video, audio, bullet lists, etc. Furthermore, the structure of a web page is also created using HTML.

CSS = Design; Now what will be the color, background, size, border, position etc. of that content, we tell this in CSS. That is, CSS decides how the content will appear in the browser.

Suppose we are writing an article in the website in which there will be a heading i.e. title and paragraphs, in such a case HTML only tells the browser which is the heading and which is the paragraph, whereas CSS will tell what will be the color and size of those headings and paragraphs.

Why is CSS important? What are its benefits

Let’s explore the benefits you’ll gain from using CSS on your website:

Maintaining the design is easy:

Suppose we’ve created a website with 50 pages using only HTML without using CSS. Now, we want all the pages to have the same design. So, we design one page and copy-paste it to create 50 pages. There’s no problem with that. After that, we add content to all the pages.

Now the website is ready but in future if we need to make some changes in the design like we need to change the heading color of all the pages to blue then we will have to go to each page and make the changes which will be a very time consuming task.

If we use CSS then this work becomes very easy because with CSS we separate the design of the page from the content part, now when we need to make changes in the design then we can easily go to the CSS file and make the changes which gets applied to the entire website.

Website speed increases:

If we use Cascading Style Sheets, the loading speed of the web page increases because we create a separate file for CSS and when you visit any page of the website, that CSS file gets stored in your browser cache. After this, when you visit another page of the same site, your browser will not need to download that CSS file again.

But if you don’t use CSS and design your layout using HTML tables, page loading will be slow because the browser will have to interpret this table every time for each page.

Designs can be displayed according to the device:

You may have noticed that the design of some sites appears differently on desktop and mobile devices. When you print out the exam result from a website, why is only the result portion printed and the rest of the headers and sidebars are not printed.

This is because they display device-specific designs using CSS, telling the browser what to display if the device is a mobile device and what to print if the device is a printer.

How to apply CSS to a web page

You can apply CSS to a web page in three ways. Let’s explore these three ways:

1- Internal style sheet
In internal CSS style sheet, we write the CSS code inside the < head > tag of the HTML of the page where the CSS style is to be applied.

See example below:

<html>
<head>
<title>Internal CSS Example</title>
<style type="text/css">
p{color:blue;}
</style>
</head>
<body>
<p>This is a paragarph.</p>
</body>

2- External Style Sheet
In this method, we create a separate file, write the CSS code in it, save it with the .css extension, and then link this file to the HTML page where the style is to be applied.

See example below:

<html>
<head>
<link rel=”stylesheet” type=”text/css” href=”style.css”></head>
<body>
  <p>
  This is a paragraph.
  </p>
</body>
</html>

To link the CSS file, we use the <link> tag in the <head> section of the HTML.

3- Inline Style Sheet
We apply CSS properties directly to the HTML element to which we want to apply the style, using the style attribute.

<html>
<head>
<title>
  Your page title
</title></head>
<body>
  <p style="color:green;">
  This is a paragraph.
  </p>
</body></html>

Which of these methods is better

You’ve seen three ways to insert CSS into an HTML file above. Now, you might be wondering which method is better? Which method you choose depends on what you want to accomplish:

If you’re building a single-page site, you should use an internal style sheet, where you write the code inside the < head > field.

If you’re planning a multi-page website, the external file method is best. Avoid internal style sheets. Best practice is to avoid the internal method whenever possible; it makes using CSS pointless. It’s difficult to maintain and increases page size.
