To do that, add the following CSS in the “advanced customization” section of your editor:
.layout.layout_siberian_18 {
padding: 0%;
height: 100vh;
}
.layout.layout_siberian_18 ion-scroll {
width: 100%;
height: 100%;
}
You can change several variables:
padding -> space between borders.
height -> height of your menu.
width -> width of your menu.
Change it and enjoy!
To get the best result, try to have a symetric aspect.
Important information:
That modification only changes the 18th layout.
