Page viewer not setting to fill parent

[Aditya_Devalalikar (Aditya)]

How can i set the page viewer to fill parent ?
I just want all tabs set to screen width.
I even tried to set page viewer width to home width.
I searched on the community but did find any helpful solution
I attached screenshots, please tell me where i am going wrong ?

i tried that…

i seems good on my mobile but when i tested this on other small device the tabs go outside the screen.

So basically asking can i set these 3 tabs to fill complete width of screen on all the devices ?
