priority - 6Size 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 1,003 CSS pixels wide, but the viewport is only 980 CSS pixels wide. The following elements fall outside the viewport:

The element <img src="/s/images/cont…hydrologie.jpg"> falls outside the viewport.
The element <div id="nav">Navigace…Login</div> falls outside the viewport.
The element <div id="content-body" class="home">. Home…Partneři</div> falls outside the viewport.
The element <div class="links">Home | Mapa st…1</div> falls outside the viewport.
The element <div id="cc-holder"></div> falls outside the viewport.
The element <span class="cleaner"></span> falls outside the viewport.

Traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network. The history of the route is recorded as the round-trip times of the packets received from each successive host (remote node) in the route (path); the sum of the mean times in each hop is a measure of the total time spent to establish the connection. Traceroute proceeds unless all (three) sent packets are lost more than twice, then the connection is lost and the route cannot be evaluated.
