Starting with HTML + CSS

Contents • • • • • • • • This short tutorial is meant for people who want to start using CSS and have never written a CSS style sheet before. It does not explain much of CSS. It just explains how to create an HTML file, a CSS file and how to make them work together. After that, you can read any of a number of At the end of the tutorial, you will have made an HTML file that looks like this: Step 1: writing the HTML For this tutorial, I suggest you use only the very simplest of tools. E.g., Notepad (under Windows), TextEdit (on the Mac) or KEdit (under KDE) will do fine. Once you understand the principles, you may want to switch to more advanced tools, or even to commercial programs, such as Style Master, Dreamweaver or GoLive. But for your very first CSS style sheet, it is good not to be distracted by too many advanced features. Don't use a wordprocessor, such as Microsoft Word or OpenOffice. They typically make files that a Web browser cannot read. For HTML and CSS, we want simple, plain text files. Step 1 is to open your text editor (Notepad, TextEdit, KEdit, or whatever is your favorite), start with an empty window and type the following: My first styled pageHome pageMusingsMy townLinksMy first styled pageWelcome to my styled page! It lacks images, but at least it has style. And it has links, even if they don't go anywhere… There should be more here, but I don't know what yet. Made 5 April 2004 by myself. In fact, you don't have to type it: you can copy and paste ...

What is CSS? • CSS was created in 1997 for web designers to give their web pages an attractive look and experience that was not so possible before using HTML alone. • The only purpose of CSS is that it has been developed to design web pages. • CSS defines how a web page design looks and feels, and for that, it provides several properties that apply only to HTML tags. • HTML is just a markup language in which we can use specific attributes and values in tags, but it cannot create an attractive web page design. • The World Wide Web Consortium (W3C) has created CSS to solve this problem. • In HTML 4.0, all formatting could be removed from the HTML document and stored in a separate CSS file. • Today all web browsers support CSS. Required Knowledge Things to Know and have before starting learning CSS: • Use any text editor like Notepad, Not...

CSS Image Sprites

Image Sprites An image sprite is a collection of images put into a single image. A web page with many images can take a long time to load and generates multiple server requests. Using image sprites will reduce the number of server requests and save bandwidth. Image Sprites - Simple Example Instead of using three separate images, we use this single image ("img_navsprites.gif"): With CSS, we can show just the part of the image we need. In the following example the CSS specifies which part of the "img_navsprites.gif" image to show: #home Example explained: • - Only defines a small transparent image because the src attribute cannot be empty. The displayed image will be the background image we specify in CSS • width: 46px; height: 44px; - Defines the portion of the image we want to use • background: url(img_navsprites.gif) 0 0; - Defines the background image and its position (left 0px, top 0px) This is the easiest way to use image sprites, now we want to expand it by using links and hover effects. Image Sprites - Create a Navigation List We want to use the sprite image ("img_navsprites.gif") to create a navigation list. We will use an HTML list, because it can be a link and also supports a background image: #navlist - Defines the background image 91px to the right (#home width 46px + 1px line divider + #prev width 43px + 1px line divider) Tip: The :hover selector can be used on all elements, not only on links. Our new image ("img_navsprites_hover.gif") contains three navigat...
