Frame in the preview articles and separator for widget articles

Hi there,

- Try this CSS:

.site-main .post {
    border: 2px solid #000;
}

- Not quite sure if I understand but try this:

.wp-show-posts-single {
    border: 2px solid #000;
}

Hello, thanks you. The
.site-main .post {
border: 2px solid #000;
}

work good for article preview in the blog. The show posts script don't work fine:

EDIT: SOLVED WITH THE FOLLOWING SCRIPT:
.wp-show-posts-single {
border-bottom: 1px solid #e3e3e3;
padding-bottom: 15px;

I have another problem. I put recent articles via shortcode in the article and gives me the following problems:
- It use the post frame and not the WPSP frame
- When I select the display in columns (in WPSP options) I do not align them all (I tried to change the number of columns to show in WPSP options) but it leaves me an empty hole and does not allow me to adjust the size of the title (it always remains H3 and I can not put paragraph) thanks :(

if I try to change the number of columns to show at 4 instead of 3 as before:

Can you open a new topic for a different question?

I'll mark this one as resolved :)

Thanks!
