Rescan Mobile Usability: 99/100 Mobile Usability Test Quick Overview

Size 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.
The tap target <a href="http://www.sur…tact/index.htm">Contacting the University</a> and 2 others are close to other tap targets. Mobile Speed: 40/100 Mobile Speed Test Quick Overview

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

Your page has 2 blocking script resources and 12 blocking CSS resources. This causes a delay in rendering your page.…nNxtQEvl--7Ml3DGySs.js
Optimize CSS Delivery of the following:…NxtQEvl--7Ml3DGySs.css…NxtQEvl--7Ml3DGySs.css…NxtQEvl--7Ml3DGySs.css…NxtQEvl--7Ml3DGySs.css…NxtQEvl--7Ml3DGySs.css…NxtQEvl--7Ml3DGySs.css…NxtQEvl--7Ml3DGySs.css…NxtQEvl--7Ml3DGySs.css

Prioritize 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 67% of the final above-the-fold content could be rendered with the full HTML response.
Minify JavaScript

Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.
Minify JavaScript for the following resources to reduce their size by 65KiB (32% reduction).
Minifying…nNxtQEvl--7Ml3DGySs.js could save 45.1KiB (28% reduction) after compression.
Minifying…rts.js?_=1503985360219 could save 17.4KiB (50% reduction).
Minifying could save 1.7KiB (40% reduction).
Minifying…sts.js?_=1503985360220 could save 696B (55% reduction).
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: (expiration not specified) (expiration not specified) (15 minutes) (20 minutes) (20 minutes) (60 minutes) (2 hours) (4 hours)
Enable compression

Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
Enable compression for the following resources to reduce their transfer size by 33.8KiB (75% reduction).
Compressing…rts.js?_=1503985360219 could save 27KiB (78% reduction).
Compressing could save 3KiB (68% reduction).
Compressing could save 2.2KiB (61% reduction).
Compressing could save 857B (62% reduction).
Compressing…sts.js?_=1503985360220 could save 727B (57% reduction).
Minify CSS

Compacting CSS code can save many bytes of data and speed up download and parse times.
Minify CSS for the following resources to reduce their size by 542B (40% reduction).
Minifying could save 542B (40% reduction). Mobile Resources
