Although Blocs delivers a very accurate representation of your final site as you actually design it, there are times when you may need to quickly preview your site to check and test other design aspects such as interactions, scroll FX and animations. Blocs has various preview options built in that are designed to help you test your site in a more natural and comprehensive way.
In App Preview
In-app preview lets you preview your site as you would in a web browser, without having to leave the main Blocs application. To enter preview mode, simply left click the play button located on the right of the breakpoint control, or alternatively with the keyboard shortcut ⌃V.
As well as design mode, preview mode also has access to the main breakpoint controls. These controls can be used to quickly and easily switch between different screen sizes, in order to check the responsive characteristics of your site.
In app preview also gives you access to the powerful WebKit developer inspector tools. The inspector tools are a great way to inspect the code of your site and debug any potential issues you are encountering. They can be accessed using the menu button in the top left of the preview frame.
Or alternatively by simply right clicking any element on a page (whilst in preview mode) and selecting Inspect.
Preview In Browser
As well as in app preview, Blocs also lets you quickly preview your site with any of the browsers you have installed on your Mac. To preview your site in a browser simply right click the preview button and select a browser from the popup menu.

Local Network Preview
The Blocs preview server can also be accessed from any device on the same network as your Mac. If the page being previewed has its file type set to .html, then a small button with an antenna symbol will be displayed in the top left corner of the main application frame. Clicking this button will copy the local network URL to your Macs pasteboard. Entering this URL into a web browser on any device that is connected to the same network as your Mac, will allow you to preview and test your site on the actual device.
