I need to make a corporate website on the layout, while using Office 365 Online (or SharePoint Server 2013) and SharePoint Designer 2013 (the latter is optional). I had absolutely no experience with SharePoint before, and had not even heard about it (and in general, I am still a student).
All that needs to be implemented on it is a news feed and gallery (obviously, with a normal addition, and not through the code). Layout design is nothing complicated, the main problem is SharePoint.
If you have met with detailed (based on zero knowledge of SharePoint) text or video lessons (tutorials) (at least in English), I will be extremely grateful for your tip.
PS The fact is that after creating the site, in the settings you can choose the design, but there is no download function or creating your own design. Hence the question. How to create your own design for SharePoint?
Thank!
