yes, i can set the width of the tablet mode separately, but that is not the point. When i want a small layout in the desktop view, for example 900 px width, then the "switch-point" to the tablet-mode will not reduce simultaneously with the smaller site set-up, the switch-point persists on a wider set-up (about 1000 px oder so ...?). Is this "switch-point" fixed or can i reduce this to another value?
UPDATE:
meanwhile .... i think ...
The setup of a page width ist usefull when responsive design ist disabled. Then you can set it to a small value like 600px or so, if you want ...
With responsive design activated the best value ist the default (1100px), you can set it a little bit smaller (1000px) for some reasons, but all smaller values are not useful. This has to do with the concept of the bootstrap framework. The device-modes and widths are predefined, so if you only change the width in the (big)desktop view you get a "inconsistence look" in relation to the other modes. So, if you want a small desktop width AND responsive design it necessary to modify the whole bootstrap framwork related to the grid system, device-modes, etc., i think TemplateToaster will not do this at the moment.
