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 49% of the final above-the-fold content could be rendered with the full HTML response.

Minify CSS for the following resources to reduce their size by 78.1KiB (19% reduction).
Minifying http://tandfonline.com/pb/css/t1493810813243-v1487…000/head_4_698_700.css could save 77.6KiB (19% reduction).
Minifying https://crossmark-cdn.crossref.org/widget/v2.0/style.css could save 533B (18% reduction).
