Layouts

Common grid layout patterns used throughout Dialpad and UberConference.

Sidebar

Use .d-gl-sidebar to create a simple 2-column layout with a sidebar and main content area.

CSS Variables

CSS Var Output
var(--sidebar-width) minmax(20rem, 30rem);
var(--content-width) minmax(32rem, 90ch);

Example

Header

Use .d-gl-header to create a simple 2-row layout with a header area and main content area. Usually this is nested within a .d-gl-sidebar content area.

CSS Variables

CSS Var Output
var(--header-height) minmax(6.4rem, min-content);
var(--content-height) minmax(64rem, max-content);

Example

Example

Nesting Grids

Unlike some CSS, CSS grid does not cascade beyond the parent and its direct children (parent-element > *). We can use this to our advantage by being able to nest grids within each other without cascade errors.
