Hi, this is my cover of the thesis. I don't know why the elements, such as the title or the red logo of the University, are not centered (vertically) into the main rectangle (the main rectangle shows the boundary of the paper). I add the \hspace but I want to know if there is a system that automatically put in the center (vertically) the object. I tried with \centering but every time every elements aren't perfectly in the center (vertically) of the main rectangle. Thanks

Answer 1

If I understand your question correctly, you would like to center your text vertically. For this, you should add a \vspace*{\fill} right after the \begin{titlepage}, and a \vfill right before the \end{titlepage}. (Sorry, if this was not your question.) I also changed encoding to utf8.
