Hi Mohammad,
In my attempt to create a presentation, I used this line of CSS to set the tiddler-height:
body.tc-body .tc-tiddler-frame {
border: 0;
margin: 0;
padding-top: 0;
min-height: 100vh;
}
I am not sure if you can use the story view width and hight in TW 5.1.16, but for me this worked great as it uses a percentage of the viewport (browser window) – 100 % in my case. The entities available are
vh = viewport height
vw = viewport width
All the best,
Thomas
