An Introduction To CSS Programming: Syntax And Basic Concepts

CSS or Cascading Style Sheets have become a really popular programming language in recent times and a lot of people are making use of CSS in designing their web pages. CSS can be used to describe how the different HTML elements can be displayed on the screen. It helps you to save a lot of time.

The concepts of CSS tutorial with example are also quite easy to understand. Once you have a complete idea of the syntax, you will easily be able to design your sheets using CSS:

1. CSS syntax

CSS syntax is a pretty basic one and consists of selector and declarations to style HTML elements.

The basic syntax for a CSS rule is as follows:

selector {

property1: value1;

property2: value2;

...

}

Any HTML element, such as a tag or class, can serve as the selector. The values are the settings you wish to apply to those properties, such as blue or 16px, and the properties are the attributes of the HTML element that you want to style, such as color or font-size.

2. Selectors

Selectors are used to specify the HTML elements to which styles should be applied. In CSS, there are various selector kinds, such as:

• Element selectors - These select elements based on their tag names, such as "p" for paragraphs or "h1" for headings.
• Class selectors - You can use class selectors to select elements based on the value of their "class" attribute. 
• ID selectors - These select elements based on the value of their "id" attribute. IDs are unique to each element, so you can use them to target specific elements. 
• Attribute selectors - The elements are selected based on the value of their attributes.

3. Properties

Properties are the attributes of HTML elements that you can change with CSS. There are many properties in CSS, but some of the most common ones include:

• Color - This property sets the color of the text.
• Font-size - This property sets the size of the font.
• Background-color - This property sets the background color of an element.
• Border - This property sets the border of an element.
• Margin - This property sets the space between an element and its surrounding elements.
• Padding - This property sets the space between an element's content and its border.

4. Values

Values are the settings you apply to properties. There are many values in CSS, but some of the most common ones include:

• Colors - CSS supports a wide variety of color values, including named colors like "red" and "green", hexadecimal values like "#FF0000" and "#00FF00", and RGB values like "rgb(255, 0, 0)".
• Lengths - Length values are used to specify sizes and distances, such as font sizes and padding. They can be expressed in pixels, Ems, or other units.
• Keywords - Some properties support keywords as values, such as "none" for the border property or "auto" for the width property.
• URLs - Some properties, such as background-image, allow you to specify URLs to images or other resources.
