Placing image caption to the left, changing font style

Hi there,

can you share a link to a page on your site where you want to apply this style ?

Sure

Tricky without using custom HTML.
But you can try adding this CSS:

@media(min-width: 1025px) {
    .wp-block-image figure.alignleft figcaption {
        position: relative;
        left: calc(-100% - 20px);
        text-align: right;
        font-style: italic;
        color: #ccc;
    }
}

you can adjust the min-width to set what size screens it applies to.
And it will only apply to images that have been left aligned

Thanks!

Sorry I missed the other requests, I updated the CSS above to include them
