Strange question maybe but my viewport camera is skewed on a weird angle. (like 35-45 degrees) wondering how to fix it.
In the 3D view, press N to show the Properties panel if it's not already showing.
Select the camera object and the Properties panel will show the Location (X, Y & Z) and its Rotation (X, Y & Z).
You can enter any values you want in those fields.
Alternatively, in the same Properties Panel, with the Camera selected, check Lock Camera To View. Now when you change the view, the camera will be updated. When you're happy with the angle of the camera, uncheck Lock Camera To View. Fine tune it by editing the fields as mentioned above.
