Gradients are a simple way to create striking website pages with a few simple clicks. Simple combine the Background Colour swatch, with a Background Gradient swatch and use the Gradient Angle tool to determine the linear angle.
Experiment by also adding a Background Overlay colour on top of your Gradient. Or use another Frame as an additional layer to create more complex Gradients with many colours at different angles.
In addition to your branded colours, you may also add a custom gradient colour simply by adding a hex code or using the colour picker to play with colours.
