How to show 3 posts per row instead of 4 when using default homepage

Hi there,
To show 3 posts per row instead of 4 when using default homepage, you can go to Dashboard / Appearances / Customize / Custom Code, and add the code below to Header Code section:

  <style>
@media (min-width: 769px) {
.block {width: 33%!important;}
}
</style>

Hope this helps!

It did, thank you very much. I noticed the thumnails became larger because of expansion to the regular 4 posts per row length. Is there a way to change the width of this box so that the thumbs are not so huge?

Hi,
To resolve this issue, you can change the code above to the following code:

  <style>
@media (min-width: 769px) {
.block {width: 33%!important;}
}
@media (min-width: 1200px) {
.home #main,.category #main {width: 900px;}
}
.block.head .block-inner {padding: 30px 10px 30px 30px!important}
</style>

Hope this helps!
