It's amazing that when you hover the mouse over a link, it shows a preview of the website.

This is a technique I've always wanted to possess, but now it's finally achievable. You just need to place a line of code on your website or blog to make it happen. Since it's in English, I'm worried some friends might not understand it, so I have a detailed Chinese-English对照 guide on my blog, which is easy to comprehend. I've already successfully applied it on my blog. I highly recommend it, and since it's originally created by me, please credit the source if you repost it. Thank you.
