Bootstrap is a popular open-source CSS framework for responsive, mobile-first front-end development. If your WordPress theme uses Bootstrap, WS Form can output form HTML markup that is native to that framework.
WS Form physically changes the HTML so your form fits seamlessly into your theme. It also changes the breakpoint selector to match the available breakpoints in Bootstrap.
WS Form supports Bootstrap 5+, Bootstrap 4.1-4.5.x, Bootstrap 4.0, and Bootstrap 3.x. All available WS Form field types are fully compatible with Bootstrap.
When you install WS Form, it scans your theme files and automatically uses Bootstrap markup if Bootstrap is detected. You can also select Bootstrap manually in WS Form settings.
