layout with sidebar
The layout-with-sidebar
component is a generic layout utility for creating two column layouts where
- One column is a sidebar with a chosen optimal width
- The other column takes up the rest of the available space
- The layout automatically wraps into one column based on a minimum percent-based width for the non-sidebar element
The purpose of the layout-with-sidebar
is to enable responsive 1-2 column layouts without the necessity of media query breakpoints. It is based on Every Layout’s Sidebar.
Branding
The layout-with-sidebar
component can be used in any brand context. You just need to import the component itself:
@import '@springernature/elements/components/layout-with-sidebar';
Usage
Default settings
Using the default settings, the l-with-sidebar
element will be 400px
in the 2-column configuration. Both columns grow to 100% width of their parent l-with-sidebar
where they wrap into 1 column. By default, this happens when the non-sidebar (“Main content” below) becomes less than 50%
of the total width.
<div class="l-with-sidebar">
<div>
Main content
</div>
<div class="l-with-sidebar__sidebar">
Sidebar content
</div>
</div>
Sidebar on left
Somewhat unconventional, but the component can take it!
<div class="l-with-sidebar">
<div class="l-with-sidebar__sidebar">
Sidebar content
</div>
<div>
Main content
</div>
</div>
Custom settings
The layout-with-sidebar
component’s settings are mapped to CSS custom properties, meaning you can alter them inline.
In the following example, the gap
between the columns is 2em
, the 1-column layout is triggered when the main content goes under 66.666%
, and the sidebar is 300px
wide in the 2-column layout.
<div class="l-with-sidebar" style="--with-sidebar--gap: 2em">
<div style="--with-sidebar--min: 66.666%">
Main content
</div>
<div class="l-with-sidebar__sidebar" style="--with-sidebar--basis: 300px">
Sidebar content
</div>
</div>
Note that these custom values will not take effect in IE11, which retains the original values, with no impact on the accessibility of the content.
