Magazine layout crashed

Hi Tom,

I encountered a major problem, I cannot solve...

I use Simple CSS on my private site. With your support I once created a nice magazine layout... but that recently crashed. I updated GP + GPP, but it needn't to correspond - perhaps it was another plugin, that causes the problem. Anyway I set the site to 3 columns with masonry "on".

CSS:

/* Magazin Layout */
.masonry-post .inside-article {
	width: 400px;
    height: 300px;
	position: relative;
	overflow: hidden; 
}

.masonry-post .entry-header {
	bottom: 0;
	right: 10;
	position: absolute;
	padding: 30px;
    z-index: 10;
}

.masonry-post .post-image img {
	left: 0;
	top: 0;
	position: relative;
    object-fit: cover;
    width: 100vw;
	/*height: 100vh;*/
    height: auto;
    display: block;
	opacity: 1;
    transition-property: all;
	transition-duration: .3s;
	-webkit-transition: .3s ease-in-out;
	transition: .3s ease-in-out; 
}

In Chrome Console (F12) I can see that there are 3 columns set (grid-33) but each article uses the whole width of the container... the picture box (with title etc.) uses 1/3 on the left, 2/3 (centre and right) are not used (but the link to the article is stretched from total left to total right)...

Any ideas to fix that?

I appreciate your help!

Best regards, Sven
