BuildStrap is a page builder for WordPress pages utilizing BootStrap version 4 by Twitter.
This page builder allows users to use any themes and page templates to create responsive design that can be customized based on the 5 break points for display screen width beyond the simple responsiveness of the page.
Embed mode allows embedding iframe, video, object, and embed elements and makes them responsive automatically. Users can also load sidebar to any column. This feature makes embedding videos from Youtube, Google maps, and many other types of media very easy.
Not only making the page responsive, customize the layout of each column and row depends on the device or browser width loading the page.
