what is css ?







CSS stands for Cascading Style Sheets. It is used to style and layout web pages by altering the font, color, size, and spacing of your content, splitting it into multiple columns, or adding animations and other decorative features¹³. CSS is a rule-based language where you define the rules by specifying groups of styles that should be applied to particular elements or groups of elements on your web page³.

There are many examples of CSS that you can use to style your web pages. Here are a few examples:

- Changing the font size and color of text

- Adding borders and background colors to elements

- Creating drop shadows and rounded corners

- Changing the size and position of elements

- Creating animations and transitions²³⁵.


There are three ways to use CSS in your web pages:

- Inline - by using the style attribute inside HTML elements

- Internal - by using a <style> element in the <head> section

- External - by using a <link> element to link to an external CSS file¹.


Here's an example of how you can use inline CSS to change the color of a paragraph:


```html

<p style="color:red;">This text is red.</p>

```

Here are some examples of CSS that you can use:


- Change the color of a paragraph:

```html

p {

  color: red;

}

```


- Change the background color of a page:

```html

body {

  background-color: lightblue;

}

```


- Change the font size of a heading:

```html

h1 {

  font-size: 40px;

}

```


I hope this helps! Let me know if you have any other questions.
