Bootstrapper components

Default components

Disable in Page-layout, if you dont want to use these components.


If you want to set an offset, for example for a fixed header, you can provide data-scroll-smooth-offset at you body element within fe_page.html5 You can provide both integers or multiple element selectors, do calculate the offset height, that should be subtracted from the target offset. Selectors have the advantage, that in case you have a responsive website, the offset updates from its element height. You are able to set the animation duration by adding data-scroll-smooth-duration to the body element and data-scroll-smooth-easing for the easing function.

Example - Integer:

<body data-scroll-smooth-offset="150" data-scroll-smooth-duration="slow" data-scroll-smooth-easing="swing" id="top">
 <div id="header"></header>

Example - Selectors:

<body data-scroll-smooth-offset="#header,#highlight" data-scroll-smooth-duration="slow" data-scroll-smooth-easing="swing" id="top">
 <div id="header"></header>
 <div id="highlight"></header>
