Copy & Paste the styles of several layers to similar layers in an other project

Question

I have a project with several layers and a specific styling for each one. In a similar project I have similar layers which need to be stlyed the same way.

I could copy the style of one layer in my first project and paste it to the corresponding layer in the second project. But it takes a lot of time to do this for many layers.

Perhabs there is a way to copy the styles of several layers in the first project and paste it again to several layers in the second one? Any ideas if this is somehow possible?

For example:

I would like to copy the styles of the Layers "Landnutzung; Schadenspotenzial; Gefährdung" and paste to the corresponding layers all at once. I want to create one Style document for all three Layers and use it for the other three Layers only once.

I hope it's clear what I mean.

You have three options (as far as I know):

1. Save styles as .qml (style tab -> symbology -> style dropdown at the bottom left). Load the same way in the other project.
2. Save styles to an .xml (style tab -> symbology -> style managing (red circle, green square, blue line next to an a at the left middle)) - this does not transfer labels and attribute formulas. Load the same way in the other project.
3. Save layers to a layer definition file (right click a layer or a group -> export). This includes all style choices, but also the layers themselves. Basically this creates an excerpt of your project. Load by drag & drop.
