[steven_banks]

I would like to change the product details tab section to have a border around it, any advice on this would be great.

Thank You

You need to changes on below file,

app/design/frontend/Themepackage/themename/web/css/source/lib/_sections.less

Hi @steven_banks

Basically this is coming from _sections.less file , but as per magento 's standard directly we don't need to edit that core file.

So override this _section.less in your custom theme :

app/design/frontend/YourThemeVendorName/themename/web/css/source/lib/_sections.less

That will help you for the same !

app/design/frontend/Themepackage/themename/web/css/source/lib/_sections.less

if u have that file, if not copy one from parent theme (probably Magento Blank) and edit line 

@_tab-content-border-top-status: true

to false
