One of the most integral parts of developing a website is to test it in different screen resolutions. There are several ways to go about it but none of them are faster and smoother than TestSize. A simple web app that lets you view site in different resolutions.
Simply enter the URL and select the window size you want to test your webpage in, ranging from 240 x 320 to 1920 x 1024.
