The previous patch (675e59c) introduce initial PWA WCO support,
this patch finetunes the PWA titlebar support by ensure the
titlebar is always visible and fill 100% page (window)
width, with the following changes:
* Use margin instead of padding to ensure 'width' fills 100% page
width, so does bottom border.
Remaining PWA stuff:
The remaining PWA WCO part have inconsistent color with the actual
color that SiYuan('s titlebar) uses, thus to make the PWA titlebar
feel native, we still needs to set either:
- a "theme-color" `<meta>` attribute (suggested)
- a "theme_color" member in the PWA manifest
...which will be a seprated topic that won't be worked on in this
patchset.
Also, the titlebar bottom border might be covered by the WCO, since
it involves half-pixel border issue which seems to be by-design,
I won't address such issue in this patchset.
