    Relative-Time Element

    Relative-Time Element

    Web component extensions to the standard <time> element

    ...This allows the server to cache HTML fragments containing dates and lets the browser choose how to localize the displayed time according to the user's preferences. Every visitor is served the same markup from the server's cache. When it reaches the browser, the custom relative-time JavaScript localizes the element's text into the local timezone and formatting. Dates are displayed before months, and a 24-hour clock is used, according to the user's browser settings. If the browser's JavaScript is disabled, the default text served in the cached markup is still displayed.

    UIkit

    UIkit

    Lightweight modular front-end framework for developing web interfaces

    ...To be even more efficient, we recommend that you install one of the autocomplete plugins for your favorite IDE or code editor. This saves a lot of time, as you won't have to look up and type all UIkit classes and markup. To use UIkit's CSS and JavaScript, include the files in your own HTML and then create the markup of any of the components. When you have installed UIkit with Less sources, you can compile it and add your own custom theme. Less is the language that the UIkit styles are written in. This allows you to include customizations in the build process, rather than manually overwriting a lot of CSS rules by hand.
