Brilliant Bookmarklets

I'm a big fan of bookmarklets and use them daily to improve my workflow and assist with web development. In short, a bookmarklet is a small application you can place on a browser’s bookmark bar perform specific functions, depending on what they are coded for.

Bookmarklets are generally written in Javascript and are really easy to install and remove. Generally they work on most browsers, but personally I only use them on Chrome, my first choice for now.

Installing a bookmarklet

To install a bookmarklet all you have to do is drag it's link to your bookmark bar and boom! your good to go. Then whenever you want to use it simply click the button on your bookmark toolbar.
