You can add your own default styles instead of using Email Default Styles to override the built-in styles with your own code or to create custom styles that you can reference within your emails.
This option is for experienced web developers only. ClubExpress cannot debug or customize Custom CSS entries. Also, very elaborate CSS may be ignored by many popular email programs.
Navigate to the Control Panel > Communications Tab > Website Modules > Blast Emailing.
Click Configure - Custom CSS.
On the left is the editor panel, where you can enter any valid CSS. On the right is a listing of the global email styles, defined using the previous option. You can easily cut and paste from the right panel to the left. Click Reset CSS to clear any changes on the left and start over.
Additional Notes
Responsive websites are built using <div> tags to control layout, and external style sheets to control the appearance of elements. But emailing viewers do not recognize these options. Instead, an emailing must be built using HTML tables to control layout and embedded styles to control the appearance of elements.
The tables inserted using the row builder tools have special CSS and HTML properties that allow them to flow differently in mobile email readers. Most left/right orientation design elements will flow vertically on small devices or viewers.
The design elements inserted via the row builder will display approximately 600px wide on desktop email clients. This width is standard and designed to fit well within most left/right pane email viewers.
Most email viewers will display buttons inserted in your emails using the ClubExpress Link Builder tool as proper buttons. However, Microsoft Outlook running on PCs will display buttons as links with the specified color background. This is due to poor HTML support.
