I don't understand why a div that has 160 of width takes all width space of the div it is inside.
The trouble is here: http://www.peliculadicto.tk/tag/peliculas/ It is the sidebar.
And it causes the index of movies going down and making a big empty white space.
Now, involved div ids are: normalizador, sidebar, searchit and category2. You can take a look with the inspector element.
Any help is truly aprecciated.
