Wordpress featured image as full width-image: achieved with additional CSS

Question

...running wordpress Version 5.9.2 : i was wondering if there’s an easy way to customize the CSS for the featured image to appear with full width. At the moment the image has a huge margin - and is not full width as it appears on the page (see below) - https://www.job-starter.com/

i tried to get this to work with this WordPress theme by including some code into the custom CSS option - see below;

what is aimed: How can I set the featured images to a full width:

i tried the following code snippets in the option additional CSS:

FIGURE.block-image IMG {
max-width: 320px;
height: auto;
}


#2
FIGURE.block-image IMG {
max-width: 320px;
height: auto;
}

or

.block-image IMG {
width: 600px;
height: auto;
}

see the examination of the page:

Question: Can we get the look and feel of the theme like it is shown on the demo-pages? That would be great. Many thanks in advance. - You saved my day.

Answer 1

Your question is a little vague. If you want to make the first wp-block-image on every page 100% width, you can do this. But it will work on every page.

You need to understand better how to scope your css.

But this should work.

article .wp-block-image:first-of-type img {
    width: 100%;
}
