Specify the number of files uploaded to the vault and change the style


I want to limit the upload of only one file unconditionally.
How is it handled?

And I want to delete the “Drag & drop files or folders here or” that is gathered in the default background, move the “Browes files” button to the right, and set the vault height to 100px.
What should I do?

Please provide example source.
