Decrease spaces between items on archive pages

I was analyzing some possible CSS to achieve the objective of compressing more the archive pages, and I would like to validate with you if these CSS below are the best one to use (archive page https://bit.ly/3zc67bq):

.one-container:not(.page) .inside-article {
    padding: 0 0 0 0;
}
.post {
	margin: 0 0 1em;
}
.post-image-above-header .no-featured-image-padding .inside-article .post-image {
    width: 80px !important;
}
