Stylesheets
Using CSS (Cascading Style Sheets) code, Stylesheets will give your applications a unique style, and can also help you customize the user interface further.
Designer applications in SpreadsheetWeb can use stylesheets to provide a distinctive visual design. CSS (Cascading Style Sheets) can customize the interface beyond the options available in Layout & Controls, such as adding spacing between elements or applying colors to specific fields. To change the style of an application, open Stylesheets in the Designer navigation.
Active stylesheets will be listed on this page. Click Add Stylesheet to add a new stylesheet into your application.
Use built-in appearance options first
You do not need a custom background stylesheet to choose artwork, a solid color, the theme default, or your own background image. In Layout & Controls, open Overview → Change app theme → Backgrounds. See Application Backgrounds for static and animated gallery designs, semantic accents, and image-upload options.
Keep custom CSS for additional styling that the built-in appearance settings do not cover. If an existing stylesheet also sets backgrounds, preview the application after changing either source of styling and review any overlapping rules.
Add or edit a stylesheet
Choose an existing style template or create your own CSS, either from scratch or by extending a template. Selecting a template from Style Template loads it into the Stylesheet editor, where you can modify or add CSS. Click Update to apply the stylesheet into your application.
