Configure the viewport

Your page does not have a viewport specified. This causes mobile devices to render your page as it would appear on a desktop browser, scaling it down to fit on a mobile screen. Configure a viewport to allow your page to render properly on all devices.
Size content to viewport

The page content is too wide for the viewport, forcing the user to scroll horizontally. Size the page content to the viewport to provide a better user experience.
The page content is 982 CSS pixels wide, but the viewport is only 980 CSS pixels wide. The following elements fall outside the viewport:
The element <div id="topBar"></div> falls outside the viewport.
The element <div id="pageContainer">Startseite…g Impressum</div> falls outside the viewport.

Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 2 blocking CSS resources. This causes a delay in rendering your page.
Optimize CSS Delivery of the following:
https://www.uni-heidelberg.de/css/style.css
https://www.uni-heidelberg.de/css/style_startseiteN.css
Leverage browser caching

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources:
