Overview
An image. Part of the Bolt “Components” CSS framework that powers the Bolt Design System.
Install via NPM
npm install @bolt/components-image
Image sizes
IMPORTANT: This method of adding classes to images is DEPRECATED.
To specify image size (e.g u-bolt-width-1/1) pass the correct class like so:
{% set classes = create_attribute(imageAttributes | default({})).addClass([
"c-bolt-image__img",
"u-bolt-width-1/1",
])
%}
Then pass it into the component:
{% include '@bolt-components-image/image.twig' with {
src: "/images/placeholders/tout-4x3-climber.jpg",
alt: "A Rock Climber",
imageAttributes: classes,
} only %}
Usage
{% include '@bolt-components-image/image.twig' with {
src: "/src/images/turtle.jpg",
alt: "A Turtle"
} only %}
