[tw5] Re: [tw] Using Custom Font in Tiddler Editor

[Maurizio Torchio]

 thank you Charlie and Jeremy! yes: mine is a font-face. 
the problem is: I love fonts! I use different fonts for different wiki, 
they embody the "soul" of the wiki (and I'd like to have the same font 
whether desktop or mobile, viewing or editing). that's why until now i used 
the edit widget for editing. but this means: no toolbar, and it can be 
annoying, especially on mobile. 
anyhow: thanks again for this priceless tool!

 As per the screenshot, the editor is showing that funky font.

 However, it did strangely take half-a-minute or so for that font to 
 take effect.

Have you tried using the CodeMirror plugin? It allows you to change the editor 
font family through $:/ControlPanel settings panel

 Works A-1 for me.

 Maybe Brush Script MT cursive doesn't work with your web browser?  
 (Another screenshot for the proof in the pudding, with an obnoxious font 
 size, below.)

 It is the font in the editor that you want adjusted, right?

 Total aside: "bubba" because it is easy for me to find and remember.  
 I'm a huge fan of the movie Forrest Gump, and really liked "Bubba" in that 
 movie.

Hi Maurizio,

That’s great to hear, I’m sorry I didn’t mention that option before.

PS - do send a screenshot of what you’ve ended up with, it might inspire

[tw5] Re: [tw] Using Custom Font in Tiddler Editor

[Maurizio Torchio]

 Hi Charlie, using a local font file, i.e

@font-face {
font-family: 'CormorantGaramond';
font-style: normal;
font-weight: 400;
src: url(./tiddly/CormorantGaramond-Regular.ttf);
}

does not work (it works anywhere in the wiki, but not in the EditTemplate).
anyhow, even if it worked, I prefer to have a single file (that's why i use 
this method to embed my font-face: http://kookma.webfonts.tiddlyspot.com/)

summing up: *CodeMirror plugin solves the problem *(and of course adds 
other nice functionalities too) *BUT the EditorToolbar does not stick 
anymore* (to the top of the screen when scrolling). ie.

div.tc-editor-toolbar {
position: sticky;
top: 0;
}

does not work anymore. 
(having a sticky toolbar is quite useful for me in mobile mode). (i tried 
to change to visible the overflow in CodeMirror to no avail). 

thank you very much anyhow!
maurizio
