3. as a last fallback, compensate for the scrollbar taking up space in the layout
|
||
|
|
by playing with the paddings. the default below will add a right padding
|
||
|
|
of the scrollbar width and clear that on hover.
|
||
|
|
this won't work well on classes that also need to set their padding,
|
||
|
|
so this needs to be overriden and adjust the padding with calc like so:
|
||
|
|
```
|
||
|
|
body.mx_scrollbar_nooverlay .componentClass.mx_AutoHideScrollbar_overflow:hover {
|
||
|
|
padding-right: calc(15px - var(--scrollbar-width)) !important;
|
||
|
|
}
|
||

|
```
