Once you really get into customizing your blog template, look, design, and functions, you may run into some cross browser compatibility issues. What does that mean? Basically, your site may not look the same in Internet Explorer as it does in Mozilla. Your site may not look the same on a PC as it does on a Mac. This can be very frustrating because new designs are often a labor of love.
There's nothing more frustrating than finding out your design/coding only works correctly on Firefox or only on IE.
So without having to buy a Mac and a PC, and without having to install every operating system known to man. Well, there's an easy solution, and it is FREE!
Visit browsershots.org. Enter your URL or page you want to test. Then check off the browsers you'd like to use. Click submit.
Refresh the page in a few minutes and the system will have uploaded screenshots of your site in all the browsers you selected. Then, you can verify for yourself that your page is in fact displaying correctly. If not, you'll see that too.
Give it a try, and let us know how it went.
