"Cascading Style Sheets (CSS) is a style sheet language that allows authors and users to attach style (e.g., fonts and spacing) to structured documents (e.g., HTML documents and XML applications). By separating the presentation style of documents from the content of documents, CSS 2.1 simplifies Web authoring and site maintenance." (From the World Wide Web Consortium's CSS 2.1 Specification)
CSS is used to style and format your website. Unless you specify a custom stylesheet, your website uses Blackbaud NetCommunity default stylesheets. When necessary, you can create custom stylesheets in Stylesheets that override a Blackbaud NetCommunity default style.
Note: The editing and designing of your website is beyond our scope of support. Consult with a qualified web developer or your account manager for information on Blackbaud services.
