Many thanks Andrii, this was very helpful.
I am facing a weird problem and I have one question. First, the problem:
When I am in my site’s homepage (http://www.jetdrops.com/) and I scroll up, a post (quote) is reappearing and makes my homepage looks like that: https://dl.dropboxusercontent.com/u/153498/to%20delete/Wrong.png while it should look like that: https://dl.dropboxusercontent.com/u/153498/to%20delete/Correct.png Any idea on how could this be fixed?
And here’s the question:
How can I make portfolio pages that will show only portfolio items that have a specific tag?
Many thanks in advance,
Dimitris
