Acr.org Test Results
acr.org Mobile Usability: 64/100
Quick overview:
Size 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 1,000 CSS pixels wide, but the viewport is only 411 CSS pixels wide. The following elements fall outside the viewport:
The element
<span class="toolbar noprint"> falls outside the viewport.
...
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 id="header_SocialL…Links_hlLink_0" href="https://www.fa…egeOfRadiology"></a> and 9 others are close to other tap targets.

acr.org Mobile Speed: 50/100
Quick overview:
Optimize images
Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by 355.7KiB (56% reduction).
Compressing http://www.acr.org/images/ACR/common/icon_donate.png could save 51KiB (99% reduction).
...
Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 3 blocking script resources and 4 blocking CSS resources. This causes a delay in rendering your page.
None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.
http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js
...
Optimize CSS Delivery of the following:
http://www.acr.org/css/ACR/main.css
...
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:
http://www.acr.org/css/ACR/acr-jqueryui-theme/jquery-ui-1.8.16.custom.css (expiration not specified)
...
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.
56.8KiB of the HTML response was required to render the above-the-fold content. This requires 3 network round-trips. Prioritize the above-the-fold content so that it can be rendered with only the first 2 round-trips' worth of HTML.
Only about 9% of the final above-the-fold content could be rendered with the HTML delivered within 2 round-trips .
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 25KiB (78% reduction).
Compressing http://www.acr.org/WebResource.axd?d=G4PLpUZyRjc4bIcj-qw0k_ACFRQ1h4nD1a1Y7V9qZ36mfSPJDRnKGcy2JDG4IcAVziek4g3tecbk2OXDE_2taSYaQn6fEJmD-gZAziERhvadEj-v0&t=635802997220000000 could save 21KiB (79% reduction).
...
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 23.2KiB (40% reduction).
Minifying http://www.acr.org/js/ACR/modernizr-2.6.2.js could save 10.1KiB (66% reduction) after compression.
...
Reduce server response time
In our test, your server responded in 0.32 seconds. There are many factors that can slow down your server response time. Please read our recommendations to learn how you can monitor and measure where your server is spending the most time.
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 7.4KiB (24% reduction).
Minifying http://www.acr.org/css/ACR/main.css could save 4.8KiB (22% reduction) after compression.
