How to add and change line separators

Greetings,

I would appreciate assistance with the following line separator issues for http://bit.ly/1wJQy7F

1) Please advise how to add the gray dotted line separator which appears between module 5 post links to also appear between module 6 and 7 post links as per: http://www.screencast.com/t/0FEVr5lro

2) Please advise how to replace the top and bottom module solid line separators with dotted lines as per: http://www.screencast.com/t/de0vl1wa7Wd

3) Please advise how to either remove or replace the header logo line separator with a transparent line as per: http://www.screencast.com/t/kMlZXyCb
<!– copy and paste. Modify height and width if desired. –>

4) Please advise how to reduce module line separator padding so that there is less space between top and bottom borders and post links.

Thank you.

Hi

1. try this css in theme panel > custom code > custom css:

.td_module_6, .td_module_7 {
border-bottom: 1px dotted grey;
margin-top: 10px;
}
.td_module_6 .td-module-thumb, .td_module_7 .td-module-thumb {
margin-bottom: 6px;
}
.td_module_6 .item-details, .td_module_7 .item-details{
margin-bottom: 10px;
}

2. Try this css: http://screencast.com/t/DsqKny9Mi

.td_module_5 {
border-bottom: 1px dotted #f1f1f1!important;
}

3. The indicated line appear on header style 7 so you can change the header style and the line won’t apear anymore.

4.Try this css:

.td_module_5 {
padding-bottom: 8px!important;
}

Hope this help.
Thanks!
