priority - 8Prioritize visible content

Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.

The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.

Only about 38% of the final above-the-fold content could be rendered with the full HTML response.

Some of the links/buttons on your webpage may be too small for a user to easily tap on a touchscreen. Consider making these tap targets larger to provide a better user experience.

The following tap targets are close to other nearby tap targets and may need additional spacing around them.

The tap target <a href="/blogy-a-rozho…-skolu-v-praze">rozhovoru ze 13. 3. 2019</a> is close to 1 other tap targets.
The tap target <a href="/banners/czech-research"></a> is close to 1 other tap targets.
The tap target <a href="https://vedavy…m.cz/?start=10" class="pagenav">2</a> and 6 others are close to other tap targets.
The tap target <a href="/politika-vyzkumu-a-vyvoje">Politika výzkumu a vývoje</a> and 12 others are close to other tap targets.
The tap target <a href="/o-projektu/o-projektu">O projektu</a> and 5 others are close to other tap targets.

vedavyzkum.cz HTML validation

Warnings

Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.

Line: 109 Column: 21 - 41
"... <section id="g-Main"> ..." Line: 163 Column: 21 - 41
"... <section id="g-Logo"> ..." Line: 221 Column: 21 - 47
"... <section id="g-navigation"> ..."

The “navigation” role is unnecessary for element “nav”.

Line: 239 Column: 1 - 69
"... <nav class="g-main-nav" role="navigation" data-g-hover-expand="true"> <..."

The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.

Line: 2641 Column: 49 - 91
"...et="_top"><img src="https://toplist.cz/dot.asp?id=1731175" border="0" alt="TOPlist" width="1" height="1"/></a> <..."

Errors

Bad value “” for attribute “alt” on element “input”: Must not be empty.

Line: 368 Column: 229 - 359
"...at..." /> <input type="image" alt="" class="button" src="/images/search.png" width="25" height="25" onclick="this.form.searchword.focus();"/> <inp..."

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

vedavyzkum.cz Ping

Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source.

vedavyzkum.cz TRACEROUTE

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.
