Hi Ramesh,
If the file is named styles.css, make sure you use styles.css with a lowercase "s" in `oxf.fr.css.custom.uri.*.*`, as some file systems are case-sensitive.
And you don't need to set `oxf.xforms.minimal-resources` and `oxf.xforms.combine-resources` to true, as this is the default.
Then I'd check if you CSS is loaded, by adding to the CSS a rule like `* { color: red }`. If that works, then you can go ahead and style the page. As usual with those things, a tool like the Chrome Dev Tools is your friend.
Finally, no, you don't need to restart the server when changing the CSS, or modifying the aforementioned properties.
