AdSense is a popular way for owners of websites to run content targeted ads on their sites. You are allowed to run up to three AdSense blocks on one page. One of the problems of running ads on your site is that if you click your own AdSense blocks you will be banned from the system and your latest payment will never be payed out to you.
1. File size
Early web designers found out that a table could be used to position content on a page. Tables where never intended to be used for layout but worked good and was easy to learn. Not only is a complex design with tables nested inside other tables difficult to understand when looking at the code -the size of the page can easily reach 60 KB+. When the code for the page outweighs the content of the page you have a problem and that is a problem which is easy to get when using nested tables since they need lots of code. With CSS you will use much less code and your page size will shrink dramatically.
2. Usability/accessibility
CSS layout is a must for a website that should have high usability and accessibility. For example, by specifying font size in “em”s, someone who has bad eyesight is able to view text on your site in double its size. A layout made in CSS degrades gracefully in browsers that do not support CSS, a site made with tables do not. The point is you can not know how a visitor to your site will browse it, with a CSS based design you know that the content will be fine if they browse it with some unusual program.
I used to do web graphics in Adobe ImageReady which came with older versions of Adobe Photoshop. Since I got a new workstation I also upgraded all my software and I am currently using the latest Adobe Photoshop CS3. ImageReady is not available anymore in CS3 since it has been integrated into the new Photoshop.
So this is how you can make an animated GIF in Photoshop CS3.
So you want to be a web developer. You have made a couple of personal homepages in basic HTML and even added your own personal gallery. You even know some tags in your head without needing to look in a guide or book and most amazing you go to sleep and wake up with knowing that #cccccc means light gray.
So this is it, you are ready for prime time. It is time to show the world what you can do and make websites for real making money of your hobby.
I want to stop your daydream right here and instead take a realistic view of what it takes to make it in the real world of web design and web site making.
