Would you be kind and possibly review the following script and help me with any possible improvement and correction?

The code has to run on a blog with a goal of being fast, and it has to be compatible with all versions of web browsers (e.g., IE, Chrome, Safari, etc.).

Sorry about my programming style, which looks like a minified code. If the code is not appropriate, please comment and I will delete the question.

Thank you so much for your time!
