In SP 2010 when I had a library in a page the library name displayed a nice soft blue line/border underneath the library name..
When I have the same library in SP 2103 only the Library name displays.
Any suggestions..note for SP2010 its all oob
The UI for 2013 was changed in many places.
You can add your own CSS style overruling SharePoints style definition
<style>
.pageTitle{
border-bottom:blue;
}
</style>
Several places you can add your own stylesheet
