Learn CSS Basic to Advance in 7 Days
Introduction
Welcome to the first day of your CSS learning journey. CSS, or Cascading Style Sheets, is a language used to style the HTML of a web page. With CSS, you can change the colors, fonts, and layout of your web pages. This article will cover the basics you need to start using CSS.
What is CSS?
CSS stands for Cascading Style Sheets. It is used to control the appearance of web pages. With CSS, you can style elements, such as headings, paragraphs, and divs, in a web page. CSS allows you to separate the content of your web page from its design.
Basic Syntax
CSS is written in rules. Each rule has a selector and a declaration block. The selector is the HTML element you want to style. The declaration block contains one or more declarations separated by semicolons. Each declaration includes a property and a value, separated by a colon.
Here is an example of a CSS rule:
p {
color: blue;
font-size: 14px;
}
In this example, the selector is "p" which stands for paragraph. The declarations change the color of the text to blue and set the font size to 14 pixels.
CSS Selectors
Selectors are used to target HTML elements. There are several types of selectors in CSS:
- Type Selector: Selects elements by their type, such as
p
for paragraphs orh1
for headings. - Class Selector: Selects elements by their class attribute. Use a dot (.) before the class name. For example,
.myClass
. - ID Selector: Selects elements by their id attribute. Use a hash (#) before the id name. For example,
#myId
. - Universal Selector: Selects all elements in a document. Use an asterisk (*).
- Attribute Selector: Selects elements with a specific attribute. For example,
input[type="text"]
selects all text input fields.
Working with Colors
CSS allows you to use different types of values for colors:
- Color Names: Basic colors like red, blue, green.
- Hex Codes: A six-digit code representing the amount of red, green, and blue. For example,
#ff0000
for red. - RGB: Specifies the amount of red, green, and blue. For example,
rgb(255, 0, 0)
for red. - RGBA: Same as RGB, but includes an alpha value for transparency. For example,
rgba(255, 0, 0, 0.5)
for semi-transparent red. - HSL: Stands for hue, saturation, and lightness. For example,
hsl(0, 100%, 50%)
for red. - HSLA: Same as HSL, but includes an alpha value. For example,
hsla(0, 100%, 50%, 0.5)
for semi-transparent red.
