The CSS files of your website may have several redundant rules that are no longer used by any element on the web pages. For instance, you may have added a site search box on your website and associated styles went into the stylesheet. Later, if you decide to remove that search box, the styles may continue to exist in your CSS though they aren’t being used anywhere. These unused entries in your CSS files increase the page load time of your website and also affect the site’s performance as the browser has to do extra work parsing all the extra rules. And even if the impact on performance is minimal, it would make your task of maintaining CSS easier if the files are kept clean and well-structured.

Is there any software program available that can remove password protection from PDF files? One that doesn’t cost a dime and works on both Mac and Windows? Well the answer is yes and that too is already installed on your computer. It’s called Google Chrome. Google Chrome has a built-in PDF reader* and a PDF writer and we can combine the two features to rem...

One of the very first Photoshop skills we learned in my tenth grade photojournalism class was cropping the background out of images. I hated it. It was extremely time consuming, and the magnetic lasso tool never seemed to want to cooperate with me. Nearly a decade later, the tools have gotten better, but there still isn't a quick and simple way for people without polished photo-editing skills to remove the background from an image. But James Diebel and Jacob Norda, the team behind a new free web app called Clipping Magic , hope to change that by doing it for you almost instantaneously. or you can try a tool given below   Adobe Photoshop contains tools like the background eraser and an extract filter to help you quickly erase complicated background images from digital photographs. Want to do something similar but without Photoshop ? Just upload your picture to FotoFlexer , an online photo editor, and open the Geek tab. There you’ll find an intelligent tool called "Smart Scisso...
