, where:
<type>
can bemin-width
,max-width
,min-height
ormax-height
<value>
is a fractional number<unit>
can bepx
,pt
orsp
If the unit is omitted, px
is assumed.
See adw_breakpoint_condition_new_length()
.
Examples:
min-width: 500px
min-height: 400pt
max-width: 100sp
max-height: 500
Ratio conditions are specified as <type>: <width>[/<height>]
, where:
<type>
can bemin-aspect-ratio
ormax-aspect-ratio
<width>
and<height>
are integer numbers
See adw_breakpoint_condition_new_ratio()
.
The ratio is represented as <width>
divided by <height>
.
If <height>
is omitted, it’s assumed to be 1.
Examples:
min-aspect-ratio: 4/3
max-aspect-ratio: 1
The logical operators and
, or
can be used to compose a complex condition
as follows:
<condition> and <condition>
: the condition is true when both<condition>
s are true, same as when usingadw_breakpoint_condition_new_and()
<condition> or <condition>
: the condition is true when either of the<condition>
s is true, same as when usingadw_breakpoint_condition_new_or()
Examples:
min-width: 400px and max-aspect-ratio: 4/3
max-width: 360sp or max-width: 360px
Conditions can be further nested using parentheses, for example:
min-width: 400px and (max-aspect-ratio: 4/3 or max-height: 400px)
If parentheses are omitted, the first operator takes priority.
