Ali Abdaal 1.0.1 introduced wide and full-width images in posts and pages.
To add this to version 1.0.0, add the following to your Code Injection head:
<style>
.kg-image-card img {
height: auto;
width: 100%;
}
.kg-width-wide,
.kg-width-full {
position: relative;
width: 75vw;
min-width: 100%;
margin-left: calc(50% - 50vw);
margin-right: calc(50% - 50vw);
transform: translateX(calc(50vw - 50%));
}
.kg-width-full {
width: 100vw;
}
</style>
