README
Twig extension for zicht/classes.
Installing
composer require zicht/twig-classes
Purpose
Provide easy conditionally joining of CSS classes in Twig templates.
Usage
{{ classes('art-vandelay') }} ⇒ 'art-vandelay'
{{ classes(['art-vandelay', 'kramerica']) }} ⇒ 'art-vandelay kramerica'
{{ classes(['art-vandelay' => true, 'kramerica' => false]) }} ⇒ 'art-vandelay'
{{ classes('art-vandelay', ['kramerica' => false, 'kel-varnsen' => true]) }} ⇒ 'art-vandelay kel-varnsen'
Example
When classes are manually added by checking one ore more properties, code can be quite hard to read:
{% set cx = [
image.url ? 'u-margin--b2' : 'u-margin--b0 u-text--center',
equal_height ? 'u-flex'
] %}
<article class="{{ cx|join(' ') }}">
...
</article>
With the classes
function, it becomes much more apparent which class is toggled by what property:
{% set cx = classes({
'u-margin--b2': image.url,
'u-margin--b0 u-text--center': not image.url,
'u-flex': equal_height
}) %}
<article class="{{ cx }}">
...
</article>
You can even created a nested object if you need to conditionally apply classes to multiple elements.
{% set cx = {
card: classes({
'u-margin--b2': image.url,
'u-margin--b0 u-text--center': not image.url,
'u-flex': equal_height
}),
img: classes({
'u-black u-bg--red': color == 'black'
})
} %}
<article class="{{ cx.card }}">
<img class="{{ cx.img }}">
...
</article>
