Top border for post exert

I would like to add a top border to each post exert in block 11 (color #ff823a)
see here: http://screencast.com/t/4DcLGxQva
Thank you!

I tried this code but didn’t work:

.td_block_11 {
border-color: #ff823a;
.td_block_11 {
border:padding-top: 14px;
}

Hi

Try this css ion theme panel > custom code > custom css: http://screencast.com/t/BhEC0iolM

.td_block_11 .td_module_10 .td-excerpt {
border-top: 1px solid #ff823a;
}

Thanks!
