Try it Yourself » CSS Border The CSS property defines a border around an HTML element.

CSS saves a lot of work. It can control the layout of multiple web pages all at once.

What is CSS?

Cascading Style Sheets (CSS) is used to format the layout of a webpage.

With CSS, you can control the color, font, the size of text, the spacing between elements, how elements are positioned and laid out, what background images or background colors are to be used, different displays for different devices and screen sizes, and much more!

Tip: The word cascading means that a style applied to a parent element will also apply to all children elements within the parent. So, if you set the color of the body text to «blue», all headings, paragraphs, and other text elements within the body will also get the same color (unless you specify something else)!

Using CSS

CSS can be added to HTML documents in 3 ways:

• Inline — by using the style attribute inside HTML elements
• Internal — by using a element in the section
• External — by using a element to link to an external CSS file

The most common way to add CSS, is to keep the styles in External CSS files. However, in this tutorial we will use inline and internal styles, because this is easier to demonstrate, and easier for you to try it yourself.

Inline CSS

An inline CSS is used to apply a unique style to a single HTML element.

An inline CSS uses the style attribute of an HTML element.

The following example sets the text color of the element to blue, and the text color of the

element to red:

Example

A Blue Heading

Internal CSS

An internal CSS is used to define a style for a single HTML page.

An internal CSS is defined in the section of an HTML page, within a element.

The following example sets the text color of ALL the elements (on that page) to blue, and the text color of ALL the

elements to red. In addition, the page will be displayed with a «powderblue» background color:

Example

This is a heading

This is a paragraph.

External CSS

An external style sheet is used to define the style for many HTML pages.

To use an external style sheet, add a link to it in the section of each HTML page:

Example

This is a heading

This is a paragraph.

The external style sheet can be written in any text editor. The file must not contain any HTML code, and must be saved with a .css extension.

Here is what the «styles.css» file looks like:

«styles.css»:

Tip: With an external style sheet, you can change the look of an entire web site, by changing one file!

CSS Colors, Fonts and Sizes

Here, we will demonstrate some commonly used CSS properties. You will learn more about them later.

The CSS color property defines the text color to be used.

The CSS font-family property defines the font to be used.

The CSS font-size property defines the text size to be used.

Example

This is a heading

This is a paragraph.

CSS Border

The CSS border property defines a border around an HTML element.

Tip: You can define a border for nearly all HTML elements.

Example

CSS Padding

The CSS padding property defines a padding (space) between the text and the border.

Example

CSS Margin

The CSS margin property defines a margin (space) outside the border.

Example

Link to External CSS

External style sheets can be referenced with a full URL or with a path relative to the current web page.

Example

This example uses a full URL to link to a style sheet:

Example

This example links to a style sheet located in the html folder on the current web site:

Example

How to replace text with CSS?

Replacing a text is mostly worked out on the server side. But in some circumstances, where we don’t have control over the server, or we are working under restrictions, replacing text using CSS may be a choice.
Method 1: Using Pseudo Elements and Visibility Modifier with Absolute Positioning
To start with, we wrap the text and assign it a class. This method requires very little markup.

The text “Old Text” needs to be hidden first and a new text has to be positioned exactly where the old text was. To do so, we change the visibility of this text using CSS to hidden first.

Then we add a new text at the exact same position, using the pseudo elements and corresponding explicit positioning.

Note that after is the pseudo element in use here. We use the visibility modifier once again to show the new text. The content attribute contains the new text.
