You can share symbols and other style items by saving them in a style file (.stylx), that can exist on a file system outside your project or even on ArcGIS Online. When you or another user adds a style file to a project, all of the symbols and other style items contained within it will be available in the galleries. You can view and modify the style from the catalog view.
To save a style to share, you just need to create a style in a project and populate it with symbols or other style items. You choose a file location for the style file when you create it. This .stylx file can then be shared the same way you share any other file. Once you've created a style, use the catalog view to copy style items into it or create new ones directly.
