SharePoint Online (Office 365) is a cloud-based service that helps organizations share and collaborate with colleagues, partners, and customers. With SharePoint, you can access internally developed sites, documents, lists, calendars and other information on those sites from any geographic location with internet access—the office, at home, or from a mobile device.
Branding your SharePoint Online site
In the modern SharePoint Online experience, you can easily change the look and feel of your site to match your company or organizational brand. You can customize the logo, colors, and navigation – often without writing a single line of code. Branding can be applied at the site level, to a group of sites, or to all sites within your organization.
SharePoint Online includes an updated set of default site themes that are responsive and look great on any device. With site themes, you can customize your site’s logo and colors to match your brand. Site designs provide specific layouts and other functionality for your site. Additional branding can be achieved using custom themes or site designs without worrying about something breaking when SharePoint Online is updated. Custom themes let you create additional color schemes beyond the defaults. Custom site designs let you control the site theme and other customizations like the site navigation, default applications, and other settings. Custom themes or designs can be applied to a new site when it’s created or applied to an existing site or group of sites.
Navigation
The most effective SharePoint sites (and web sites in general) help visitors find what they need quickly so that they can use the information they find to make decisions, learn about what is going on, access the tools they need, or engage with colleagues to help solve a problem. The fundamental principles and good practices for site and page navigation are equally applicable to both classic and modern SharePoint architectures. However, your options for implementing navigation differs based on the framework for your sites and intranet. For example, the “inherited” navigation experiences available in classic SharePoint site hierarchies (sites with subsites) are not available in the modern experience, but hub sites provide a great way to achieve the cross-site navigation features previously available in managed navigation and site hierarchies in classic SharePoint.
