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.

오늘하루 이창을 열지 않기 renders only 4 pixels tall (11 CSS pixels).

2016. 06. 29 renders only 4 pixels tall (11 CSS pixels).

OUTIN FUTURES Business Lounge and 234 others render only 5 pixels tall (13 CSS pixels).

포엠인베스트먼트 & 홍익투자_여의도 and 469 others render only 4 pixels tall (11 CSS pixels).

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 - 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 1,120 CSS pixels wide, but the viewport is only 980 CSS pixels wide. The following elements fall outside the viewport:

cref.co.kr 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.

cref.co.kr 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.
