Introduction

Cascading Style Sheets, fondly referred to as CSS, is a simple design language intended to simplify the process of making web pages presentable.

CSS handles the look and feel part of a web page. Using CSS, you can control the color of the text, the style of fonts, the spacing between paragraphs, how columns are sized and laid out, what background images or colors are used, layout designs,variations in display for different devices and screen sizes as well as a variety of other effects.

CSS is easy to learn and understand but it provides powerful control over the presentation of an HTML document. Most commonly, CSS is combined with the markup languages HTML or XHTML.

Advantages of CSS

CSS saves time − You can write CSS once and then reuse same sheet in multiple HTML pages. You can define a style for each HTML element and apply it to as many Web pages as you want.
Pages load faster − If you are using CSS, you do not need to write HTML tag attributes every time. Just write one CSS rule of a tag and apply it to all the occurrences of that tag. So less code means faster download times.
Easy maintenance − To make a global change, simply change the style, and all elements in all the web pages will be updated automatically.
Superior styles to HTML − CSS has a much wider array of attributes than HTML, so you can give a far better look to your HTML page in comparison to HTML attributes.
Multiple Device Compatibility − Style sheets allow content to be optimized for more than one type of device. By using the same HTML document, different versions of a website can be presented for handheld devices such as PDAs and cell phones or for printing.
Global web standards − Now HTML attributes are being deprecated and it is being recommended to use CSS. So its a good idea to start using CSS in all the HTML pages to make them compatible to future browsers.

Who Creates and Maintains CSS?

CSS is created and maintained through a group of people within the W3C called the CSS Working Group. The CSS Working Group creates documents called specifications. When a specification has been discussed and officially ratified by the W3C members, it becomes a recommendation.

These ratified specifications are called recommendations because the W3C has no control over the actual implementation of the language. Independent companies and organizations create that software.

NOTE − The World Wide Web Consortium, or W3C is a group that makes recommendations about how the Internet works and how it should evolve.

CSS Versions

Cascading Style Sheets level 1 (CSS1) came out of W3C as a recommendation in December 1996. This version describes the CSS language as well as a simple visual formatting model for all the HTML tags.

CSS2 became a W3C recommendation in May 1998 and builds on CSS1. This version adds support for media-specific style sheets e.g. printers and aural devices, downloadable fonts, element positioning and tables.

Syntax

CSS Syntax

A CSS rule-set consists of a selector and a declaration block:

CSS selector

The selector points to the HTML element you want to style.

The declaration block contains one or more declarations separated by semicolons.

Each declaration includes a CSS property name and a value, separated by a colon.

A CSS declaration always ends with a semicolon, and declaration blocks are surrounded by curly braces.

Example

In this example all <p> elements will be center-aligned, with a red text color:

p {
color: red;
text-align: center;
}

Example Explained

p is a selector in CSS (it points to the HTML element you want to style: <p>).
color is a property, and red is the property value
text-align is a property, and center is the property value

Inclusion

There are four ways to associate styles with your HTML document. Most commonly used methods are inline CSS and External CSS. Embedded CSS - The

This is a heading

This is a paragraph.

It will produce the following result − Attributes Attributes associated with tags or rules defined in any external style sheet file. Any rule defined in tags will override rules defined in any external style sheet file. Any rule defined in external style sheet file takes lowest priority, and rules defined in this file will be applied only when above two rules are not applicable. Handling old Browsers There are still many old browsers who do not support CSS. So, we should take care while writing our Embedded CSS in an HTML document. The following snippet shows how you can use comment tags to hide CSS from older browsers − CSS Comments Many times, you may need to put additional comments in your style sheet blocks. So, it is very easy to comment any part in style sheet. You can simple put your comments inside /*.....this is a comment in style sheet.....*/. You can use /* ....*/ to comment multi-line blocks in similar way you do in C and C++ programming languages. Example Live Demo

Hello World!

It will produce the following result −

Measurement Units

Before we start the actual exercise, we would like to give a brief idea about the CSS Measurement Units. CSS supports a number of measurements including absolute units such as inches, centimeters, points, and so on, as well as relative measures such as percentages and em units. You need these values while specifying various measurements in your Style rules e.g. border = "1px solid red". We have listed out all the CSS Measurement Units along with proper Examples − Unit Description Example % Defines a measurement as a percentage relative to another value, typically an enclosing element. p {font-size: 16pt; line-height: 125%;} cm Defines a measurement in centimeters. div {margin-bottom: 2cm;} em A relative measurement for the height of a font in em spaces. Because an em unit is equivalent to the size of a given font, if you assign a font to 12pt, each "em" unit would be 12pt; thus, 2em would be 24pt. p {letter-spacing: 7em;} ex This value defines a measurement relative to a font's x-height. The x-height is determined by the height of the font's lowercase letter x. p {font-size: 24pt; line-height: 3ex;} in Defines a measurement in inches. p {word-spacing: .15in;} mm Defines a measurement in millimeters. p {word-spacing: 15mm;} pc Defines a measurement in picas. A pica is equivalent to 12 points; thus, there are 6 picas per inch. p {font-size: 20pc;} pt Defines a measurement in points. A point is defined as 1/72nd of an inch. body {font-size: 18pt;} px Defines a measurement in screen pixels. p {padding: 25px;}

Colors

CSS uses color values to specify a color. Typically, these are used to set a color either for the foreground of an element (i.e., its text) or else for the background of the element. They can also be used to affect the color of borders and other decorative effects.

You can specify your color values in various formats. Following table lists all the possible formats −

Format	Syntax	Example
Hex Code	#RRGGBB	p{color:#FF0000;}
Short Hex Code	#RGB	p{color:#6A7;}
RGB %	rgb(rrr%,ggg%,bbb%)	p{color:rgb(50%,50%,50%);}
RGB Absolute	rgb(rrr,ggg,bbb)	p{color:rgb(0,0,255);}
keyword	aqua, black, etc.	p{color:teal;}

These formats are explained in more detail in the following sections −

CSS Colors - Hex Codes

A hexadecimal is a 6 digit representation of a color. The first two digits(RR) represent a red value, the next two are a green value(GG), and the last are the blue value(BB).

A hexadecimal value can be taken from any graphics software like Adobe Photoshop, Jasc Paintshop Pro, or even using Advanced Paint Brush.

Each hexadecimal code will be preceded by a pound or hash sign '#'. Following are the examples to use Hexadecimal notation.

Color	Color HEX
	#000000
	#FF0000
	#00FF00
	#0000FF
	#FFFF00
	#00FFFF
	#FF00FF
	#C0C0C0
	#FFFFFF

CSS Colors - Short Hex Codes

This is a shorter form of the six-digit notation. In this format, each digit is replicated to arrive at an equivalent six-digit value. For example: #6A7 becomes #66AA77.

A hexadecimal value can be taken from any graphics software like Adobe Photoshop, Jasc Paintshop Pro, or even using Advanced Paint Brush.

Each hexadecimal code will be preceded by a pound or hash sign '#'. Following are the examples to use Hexadecimal notation.

Color	Color HEX
	#000
	#F00
	#0F0
	#0FF
	#FF0
	#0FF
	#F0F
	#FFF

CSS Colors - RGB Values

This color value is specified using the rgb( ) property. This property takes three values, one each for red, green, and blue. The value can be an integer between 0 and 255 or a percentage.

NOTE − All the browsers does not support rgb() property of color so it is recommended not to use it.

Following is the example to show few colors using RGB values.

Color	Color RGB
	rgb(0,0,0)
	rgb(255,0,0)
	rgb(0,255,0)
	rgb(0,0,255)
	rgb(255,255,0)
	rgb(0,255,255)
	rgb(255,0,255)
	rgb(192,192,192)
	rgb(255,255,255)

Building Color Codes

You can build millions of color codes using our Color Code Builder. Check our HTML Color Code Builder. To use this tool, you would need a Java Enabled Browser.

Browser Safe Colors

Here is the list of 216 colors which are supposed to be most safe and computer independent colors. These colors vary from hexa code 000000 to FFFFFF. These colors are safe to use because they ensure that all computers would display the colors correctly when running a 256 color palette −

Fonts

This chapter teaches you how to set fonts of a content, available in an HTML element. You can set following font properties of an element − The font-family property is used to change the face of a font. The font-style property is used to make a font italic or oblique. The font-variant property is used to create a small-caps effect. The font-weight property is used to increase or decrease how bold or light a font appears. The font-size property is used to increase or decrease the size of a font. The font property is used as shorthand to specify a number of other font properties. Set the Font Family Following is the example, which demonstrates how to set the font family of an element. Possible value could be any font family name. Live Demo
This text is rendered in either georgia, garamond, or the default serif font depending on which font you have at your system.

Images

Images play an important role in any webpage. Though it is not recommended to include a lot of images, but it is still important to use good images wherever required. CSS plays a good role to control image display. You can set the following image properties using CSS. The border property is used to set the width of an image border. The height property is used to set the height of an image. The width property is used to set the width of an image. The -moz-opacity property is used to set the opacity of an image. The Image Border Property The border property of an image is used to set the width of an image border. This property can have a value in length or in %. A width of zero pixels means no border. Here is the example − Live Demo

It will produce the following result − The Image Height Property The height property of an image is used to set the height of an image. This property can have a value in length or in %. While giving value in %, it applies it in respect of the box in which an image is available. Here is an example − Live Demo

It will produce the following result − The Image Width Property The width property of an image is used to set the width of an image. This property can have a value in length or in %. While giving value in %, it applies it in respect of the box in which an image is available. Here is an example − Live Demo

It will produce the following result − The -moz-opacity Property The -moz-opacity property of an image is used to set the opacity of an image. This property is used to create a transparent image in Mozilla. IE uses filter:alpha(opacity=x) to create transparent images. In Mozilla (-moz-opacity:x) x can be a value from 0.0 - 1.0. A lower value makes the element more transparent (The same things goes for the CSS3-valid syntax opacity:x). In IE (filter:alpha(opacity=x)) x can be a value from 0 - 100. A lower value makes the element more transparent. Here is an example − Live Demo

It will produce the following result −

Links

This chapter teaches you how to set different properties of a hyper link using CSS. You can set following properties of a hyper link − We will revisit the same properties when we will discuss Pseudo-Classes of CSS. The :link signifies unvisited hyperlinks. The :visited signifies visited hyperlinks. The :hover signifies an element that currently has the user's mouse pointer hovering over it. The :active signifies an element on which the user is currently clicking. Usually, all these properties are kept in the header part of the HTML document. Remember a:hover MUST come after a:link and a:visited in the CSS definition in order to be effective. Also, a:active MUST come after a:hover in the CSS definition as follows − Now, we will see how to use these properties to give different effects to hyperlinks. Set the Color of Links The following example demonstrates how to set the link color. Possible values could be any color name in any valid format. Live Demo Link It will produce the following black link − Set the Color of Visited Links The following example demonstrates how to set the color of visited links. Possible values could be any color name in any valid format. Live Demo link It will produce the following link. Once you will click this link, it will change its color to green. Change the Color of Links when Mouse is Over The following example demonstrates how to change the color of links when we bring a mouse pointer over that link. Possible values could be any color name in any valid format. Live Demo Link It will produce the following link. Now, you bring your mouse over this link and you will see that it changes its color to yellow. Change the Color of Active Links The following example demonstrates how to change the color of active links. Possible values could be any color name in any valid format. Live Demo Link It will produce the following link. It will change its color to pink when the user clicks it.

Tables

This tutorial will teach you how to set different properties of an HTML table using CSS. You can set following properties of a table −

The border-collapse specifies whether the browser should control the appearance of the adjacent borders that touch each other or whether each cell should maintain its style.
The border-spacing specifies the width that should appear between table cells.
The caption-side captions are presented in the <caption> element. By default, these are rendered above the table in the document. You use the caption-side property to control the placement of the table caption.
The empty-cells specifies whether the border should be shown if a cell is empty.
The table-layout allows browsers to speed up layout of a table by using the first width properties it comes across for the rest of a column rather than having to load the whole table before rendering it.

Now, we will see how to use these properties with examples.

The border-collapse Property

This property can have two values collapse and separate. The following example uses both the values −
