@Jonathan: Sorry there is no layout to just show the title only in the category page. For this you need to build child theme and then work on custom template to show only post title in particular category.
Your second question answer, as you are using small images as featured image in the post. Design looks bit odd. As we created this design with large featured image. But I have css that will make your category page with small thumbnail looks good. Add the following css in “Appearance => Theme Options => Custom CSS” box.
.category .entry-summary {
height: 1%;
overflow: hidden;
}
.category .entry-summary .wp-post-image {
display: inline-block;
float: left;
margin: 0 10px 10px 0;
width: 25%;
}
If you want change the spacing then you have change it for various screensize. So, be careful and change it. You can adjust the padding and margin bottom as per your need and then add it in “Appearance => Theme Options => Custom CSS” box.
/* For Large Screen */
.hentry, .no-results, #author-info, #disqus_thread, #content .error404 {
margin-bottom: 40px;
padding: 30px;
}
/* For Max Screen Size of 1224px */
@media screen and (max-width: 1224px) {
.hentry, .no-results, #author-info, #disqus_thread, #content .error404 {
margin-bottom: 30px;
padding: 40px 38px;
}
}
/* For Max Screen Size of 767px */
@media screen and (max-width: 767px) {
.hentry, .no-results, #author-info, #disqus_thread, #content .error404 {
margin-bottom: 10px;
padding: 10px;
}
