Styles can promote consistency or standardization across multiple maps and scenes within a project. ArcGIS Pro includes system styles that are installed and available to connect to from a project. These are read-only; you cannot modify their contents. You can also create and add your own styles to projects to organize style items to suit your work. Items from system styles can be copied to custom styles and modified as you want, or you can create new style items.

Learn about finding symbols.

A project can include any number of styles. Styles added to a project are called project styles. When searching for symbols and other style items, you can choose to limit the search results to just project styles, or search from within all available styles included with ArcGIS Pro. You can remove any of these styles from the project (or connect to others) any time. Removing a style does not have any impact on symbols or other assets you have accessed from that style and placed in a map, scene, or layout.

Styles are not dependent on the current map document; items you save into them will still be accessible when you open a different map document. Also, there is no reference maintained back to the style once a style item is applied. When you select and apply a symbol, a copy of the symbol is embedded within the layer or map document. Subsequent changes you make to that symbol in your map are not reflected in the copy stored in the style. Similarly, if you later modify the symbol in the style, the change will not propagate to the symbol embedded in your map. This means you don't need access to the original styles to open and draw a map again.
