CSS Float Property

CSS Floating Columns

CSS Floating Elements

CSS Clear Float

CSS Floated Layout

Definition
The float property sets where an image or a text will appear in another element.

Inherited: No

Note: If there is too little space on a line for the floating element, it will jump down on the next line, and continue until a line has enough space.

Note: Content, background, and borders of inline elements should go in front of the float. Background and borders of a block element should go behind the float, but the content of the block element should go in front of the float.

JavaScript Syntax
CSS properties can also be dynamically changed with a JavaScript.

Scripting Syntax: object.style.cssFloat="left"

In our HTML DOM tutorial you can find more details about the cssFloat property.
In our HTML DOM tutorial you can also find a full Style Object Reference.

Possible Values
left: The image or text moves to the left in the parent element
right: The image or text moves to the right in the parent element
none: Default. The image or the text will be displayed just where it occurs in the text

How CSS Is Applied

CSS Inheritance Style

How to Insert a Style Sheet
When a browser reads a style sheet, it will format the document according to it. There are three ways of inserting a style sheet:

External Style Sheet
An external style sheet is ideal when the style is applied to many pages. With an external style sheet, you can change the look of an entire Web site by changing one file. Each page must link to the style sheet using the <link> tag. The <link> tag goes inside the head section:

Internal Style Sheet
An internal style sheet should be used when a single document has a unique style. You define internal styles in the head section by using the <style> tag, like this:

<head>
<style type="text/css">
hr {color: sienna}
p {margin-left: 20px}
body {background-image: url("images/back40.gif")}
</style>
</head>

Inline Styles
An inline style loses many of the advantages of style sheets by mixing content with presentation. Use this method sparingly, such as when a style is to be applied to a single occurrence of an element.

To use inline styles you use the style attribute in the relevant tag. The style attribute can contain any CSS property. The example shows how to change the color and the left margin of a paragraph:

<p style="color: sienna; margin-left: 20px">
This is a paragraph
</p>

Multiple Style Sheets
If some properties have been set for the same selector in different style sheets, the values will be inherited from the more specific style sheet.

For example, an external style sheet has these properties for the h3 selector:

h3
{
color: red;
text-align: left;
font-size: 8pt
}

And an internal style sheet has these properties for the h3 selector:

h3
{
text-align: right;
font-size: 20pt
}

If the page with the internal style sheet also links to the external style sheet the properties for h3 will be:

color: red;
text-align: right;
font-size: 20pt

The color is inherited from the external style sheet and the text-alignment and the font-size is replaced by the internal style sheet.

CSS Beginning with Markup

CSS Web Designers Intro: Chapter 2

CSS Introduction: XHTML Documents

CSS Semantic Elements

CSS Validation

What Is XHTML?
1. XHTML stands for EXtensible HyperText Markup Language
2. XHTML is aimed to replace HTML
3. XHTML is almost identical to HTML 4.01
4. XHTML is a stricter and cleaner version of HTML
5. XHTML is HTML defined as an XML application XHTML is a W3C Recommendation

XHTML: Why is Validation Important
Why you should make sure that your web pages are validated? Thats exactly what we’re going to answer in this tutorial. Hopefully you’ve heard off XHTML and HTML. HTML is the older coding and XHTML is the new generation of HTML. This is the web standard set by the World Wide Web Consortium (W3C) they set standards for the internet. This tutorial will use references to W3 quite often, so if you haven’t heard of them till now you might want to consider checking them out and seeing the work they do.

What is Validation?
Validation is a process of checking your documents against a formal Standard, such as guidelines published by the World Wide Web Consortium (W3C) for HTML and XML-derived Web pages. Consider Validation like Microsoft word for a moment. Imagine you’ve wrote a 5000 words essay and any spelling mistakes made would mark you down for that essay. To make sure this doesn’t happen you would use a spell checker to check grammar and spelling, you could also check it yourself, but a spell checker is more accurate. Validation is like a spell checker it is a precise process and is very reliable. Precise because it deals with languages in the ways browsers work as well as specific machine langauges.

Why Validate?
You should validate your web pages because by doing this, you know you are following web standards set by W3, validation in many people’s eyes is a real pain. This shouldn’t be the case. Validation is a very important factors of you code and design, I wouldn’t be able to thank it enough because it can say you from serious errors occurring in your code as well spot potential issues that don’t necessarily harm anything but pose a threat. Validation also shows to your visitors that you have taken care in coding your web pages and show that you follow standards set.

Do I have to follow standards?
You are not forced to validate your web pages but, by not validating your web pages your not correctly coding and you could potentially coding bad mark up without realizing it. People get confused with the fact that W3 set recommendations. They don’t make them, they make recommendations, they are however dedicated in setting standards for the world and do a damn good job.

CSS Evolution

The Future of CSS

What is CSS?
1. CSS stands for Cascading Style Sheets
2. Styles define how to display HTML elements
3. Styles are normally stored in Style Sheets
4. Styles were added to HTML 4.0 to solve a problem
5. External Style Sheets can save you a lot of work
6. External Style Sheets are stored in CSS files
7. Multiple style definitions will cascade into one

Styles Solve a Common Problem
HTML tags were originally designed to define the content of a document. They were supposed to say "This is a header", "This is a paragraph", "This is a table", by using tags like <h1>, <p>, <table>, and so on. The layout of the document was supposed to be taken care of by the browser, without using any formatting tags.

As the two major browsers - Netscape and Internet Explorer - continued to add new HTML tags and attributes to the original HTML specification, it became more and more difficult to create Web sites where the content of HTML documents was clearly separated from the document's presentation layout.

To solve this problem, the World Wide Web Consortium (W3C) - the non profit, standard setting consortium, responsible for standardizing HTML - created STYLES in addition to HTML 4.0.

All major browsers support Cascading Style Sheets.

Style Sheets Can Save a Lot of Work
Styles sheets define HOW HTML elements are to be displayed, just like the font tag and the color attribute in HTML 3.2. Styles are normally saved in external .css files. External style sheets enable you to change the appearance and layout of all the pages in your Web, just by editing one single CSS document!

CSS is a breakthrough in Web design because it allows developers to control the style and layout of multiple Web pages all at once. As a Web developer you can define a style for each HTML element and apply it to as many Web pages as you want. To make a global change, simply change the style, and all elements in the Web are updated automatically.

Multiple Styles Will Cascade Into OneStyle sheets allow style information to be specified in many ways. Styles can be specified inside a single HTML element, inside the element of an HTML page, or in an external CSS file. Even multiple external style sheets can be referenced inside a single HTML document.

Cascading Order

What style will be used when there is more than one style specified for an HTML element?

Generally speaking we can say that all the styles will "cascade" into a new "virtual" style sheet by the following rules, where number four has the highest priority:

1. Browser default
2. External style sheet
3. Internal style sheet (inside the tag)
4. Inline style (inside an HTML element)

So, an inline style (inside an HTML element) has the highest priority, which means that it will override a style declared inside the tag, in an external style sheet, or in a browser (a default value).
