demographic-research.org 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.

demographic-research.org 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.

priority - 40Use legible font sizes

The following text on your page renders in a way that may be difficult for some of your visitors to read. Use legible font sizes to provide a better user experience.

The following text fragments have a small font size. Increase the font size to make them more legible.

priority - 11Size 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 1,024 CSS pixels wide, but the viewport is only 980 CSS pixels wide. The following elements fall outside the viewport:

priority - 10Configure 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.

priority - 5Size tap targets appropriately

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.

demographic-research.org HTML validation

Errors

Almost standards mode doctype. Expected “<!DOCTYPE html>”.

Bad value “https://www.w3.org/1999/xhtml” for the attribute “xmlns” (only “http://www.w3.org/1999/xhtml” permitted here).

Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.

Bad value “imagetoolbar” for attribute “http-equiv” on element “meta”.

Bad value “cache-control” for attribute “http-equiv” on element “meta”.

No “p” element in scope but a “p” end tag seen.

Element “div” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)

Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)

Warnings

Attribute “xmlns” is not serializable as XML 1.0.

The “type” attribute is unnecessary for JavaScript resources.

Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
