Understanding the float property is fundamental to understanding CSS-based layout and design; it is one of the last pieces in the puzzle of how all these elements fit together. Briefly stated, the float property allows elements to be moved around in the design such that other elements can wrap around them. You will often find float used in conjunction with images (as you saw in previous lesson), but you can — and many designers do — float all sorts of elements in their layout.

Knowing that content on a web page doesn’t always fill the entire width of the rectangular area in which it is displayed, it is often helpful to control the alignment of the content. Even if text within a rectangular area extends to multiple lines, alignment still enters the picture because you might want the text left-justified, right-justified, or centered. There are two style properties that enable you to control the alignment of elements: text-align and vertical-align.

Padding is similar to margins in that it adds extra space to elements, but the big difference is where that space is located. If you recall, margins are added to the outside of elements. On the other hand, padding adds space inside the rectangular area of an element. As an example, if you create a style rule for an element that establishes a width of 50 pixels and a height of 30 pixels, and then sets the padding of the rule to 5 pixels, the remaining content area will be 40 pixels by 20 pixels. Also, because the padding of an element appears within the element’s content area, it will assume the same style as the content of the element, including the background color.

CSS margins enable you to add empty space around the outside of the rectangular area for an element on a web page. It is important to remember that the margin property works with space outside of the element. Following are the style properties for setting margins:

1. margin-top — Sets the top margin.
2. margin-right — Sets the right margin.
3. margin-bottom — Sets the bottom margin.
4. margin-left — Sets the left margin.
5. margin — Sets the top, right, bottom, and left margins as a single property.

You can specify margins using any of the individual margin properties or using the single margin property. Margins can be specified as auto, meaning the browser itself sets the margin in specific lengths (pixels, points,ems) or in percentages. If you decide to set a margin as a percentage, keep in mind that the percentage is calculated based on the size of the entire page, not the size of the element. So, if you set the margin-left property to 25%, the left margin of the element will end up being 25% of the width of the entire page.

Now that you’ve learned how to work with static images, the natural next step is to work with multimedia. The term multimedia encompasses everything we see and hear on a web page: audio, video, and animation, as well as static images and text. In this section, you won’t learn how to create any particular audio, video, or animation, but you will learn how to include such files in your site, through either linking or embedding the content.

Remember, though, that not every user has devices that will play your media type, nor do all users have broadband Internet connections which allow these large files to transfer quickly. Always warn your visitors that the links they click will take them to multimedia files and offer them the choice to view or listen to the content. Don’t force the files upon them!

Creating multimedia of any kind can be a challenging and complicated task. If you’re planning to create your own content from scratch, you’ll need far more than this lesson to become the next cracker jack multimedia developer. After you have some content, however, this section will show you how to place your new creations into your web pages. For those of us who are artistically challenged, several alternative ways to obtain useful multimedia assets are available. Aside from the obvious (such as hiring an artist), here are a few suggestions:

How to choose a good Web Hosting Provider

Despite just telling you that you can work through all the posts in this lesson without having a web server, having a web server is the recommended method for continuing on. Don’t worry, obtaining a hosting provider is usually a quick, painless, and relatively inexpensive process. In fact, you can get your own domain name and a year of web hosting for just slightly more than the cost of the data you spent in reading this post. If you type web hosting provider in your search engine of choice, you will get millions of hits and an endless list of sponsored search results (also known as ads). There are not this many web hosting providers in the world, although it might seem like there are. Even if you are looking at a managed list of hosting providers, it can be overwhelming especially if all you are looking for is a place to host a simple website for yourself or your company or organization. You’ll want to narrow your search when looking for a provider and choose one that best meets your needs. Some selection criteria for a web hosting provider include the following:

LESSON 1
A Brief History of HTML and the World Wide Web
Once upon a time, back when there weren’t any footprints on the moon, some farsighted folks decided to see whether they could connect several major computer networks together. I’ll spare you the names and stories (there are plenty of both), but the eventual result was the “mother of all
networks,” which we call the Internet.
Until 1990, accessing information through the Internet was a rather technical affair. It was so hard, in fact, that even Ph.D.-holding physicists were often frustrated when trying to swap data. One such physicist, the now famous (and knighted) Sir Tim Berners-Lee, cooked up a way to easily
cross-reference text on the Internet through hypertext links.
