Two related improvements. Stylesheets are considerably smaller, and a change you make in your design settings shows up immediately rather than whenever your browser decides to look again.
Every design in the catalog carries its own stylesheet, and what reaches a visitor is not the file a theme author wrote.
Premium designs now offer a sticky menu: it stays at the top of the window as the visitor scrolls, instead of disappearing after the first screen.
Type a numbered list in the editor and a numbered list appears on your website. Bold text stays bold, a heading stays a heading, and a paragraph break stays a paragraph break.
You can now add custom JavaScript to your actor website. Unlike custom CSS, it does not go live immediately. It is reviewed first, usually within a working day.
Every image on every page of all 97 designs passes through a single place that decides how hard it is compressed. That setting moved one step down.
There is now a custom stylesheet box in your design settings. What you write there is applied to your site after everything else, so it can override any rule in the design.
Two headers now go out with every page of every customer site. nosniff stops a browser from guessing that a response is a web page when the declared type says it is an image.
Every design now offers three content widths: full, which uses the whole window, contained, which is the traditional centered column, and narrow, which is tighter still.
Caching is what makes a website fast: a page is built once and the built copy is handed to everybody who asks for it, instead of being assembled from scratch every time.
There is now a font setting on every design: a curated set of pairings, each one a heading face and a body face that are known to work together.
A press kit is the single link you send when somebody needs your material and you do not want to send five attachments.
