The best way to do it is to either wrap the CSS part in triple backticks ``` or to highlight the block of CSS text and tap the </> button in the forum’s editor toolbar:
So the following text that is entered (screenshotted):
Would become:
.tile .title { line-height: 100%; }
OK. I turned the first post into a wiki and updated the formatting a bit. Feel free to adjust as you see fit though! 
Added footer line spacing
Added margin adjust to top/bottom or left/right
Hi all, this CSS editing is a lovely touch. Fine tuning my dashboards and they’re looking better than ever.
Can someone possible assist me with adjusting the calendar main body font size? The font for my actual calendar events is very very small. The tile itself it fairly large and header is a good size font
Thanks for help.
Try these, and you may adjust the font-size that fits you the best.
.tile.calendar.agenda .main-content { font-size: 1.75em; }
.tile.news-feed .main-content { font-size: 1.75em; }
Please note these CSS snippets provided are not officially supported and you may have to adjust them if there are DOM changes with future releases
-EDIT-
Updated the css slightly to apply the font size change to the whole agenda content, as well as including the font-size change for news-feed tile.
Thanks for sharing. It now looks much better and I’ve noted the caveats for future development.
Added these to the wiki
Would like to know a way to remove padding on icons using CSS.
Need to make them as large as possible, and don’t need padding since using transparent tile.
Thanks!
CSS for adjusting icon size (which I find the default size a bit too imposing). If you consider 50% being the default size for the CSS below then I use 35% as a bit smaller icon which I find much more aesthetic. Adjust percentages to your taste…
.tile .icon svg {width: 35%; height: 35%; margin: 0; position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%);}
I also added to the wiki. CSS can likely be shortened but I kinda like it in full form to play around with any of the related attributes.
I usually just target the font size of the icon. It looks like the icons are usually 4em by default, so I just adjust from there.
Half size: (2 / 4)
.tile .icon svg { font-size: 2em; }
25% bigger (5 / 4):
.tile .icon svg { font-size: 5em; }
I was trying to figure out why you had all the other stuff with positioning in your example since the icons are already centered, but I guess once you make the icons so big that they go out of their bounding box, the extra centering can help force them back to center.
Does anyone know syntax for header or title font upsizing? since the scalable updates I cannot read or update the tile title sizes. I did fix the calendar content size with the CSS per guidance above.
thanks, Mark
You can adjust it in the theme. It’s listed as “Header Font Size” toward the bottom of the customizations. You can choose the ‘Custom’ size and then input whatever percentage you want like 200%
Thank you for that; seems to work with a little trial and error. I had tried the largest non custom size and didn’t see any movement. I am assuming the theme solution is the only way to modify dashboard tile font size (for icon hero types) if scalable method is used? thanks again.
.tile .title { font-size: <specify size in points or em units>; }
-and-
.tile .title-footer { font-size: <specify size in points or em units>; }
should to the trick
Note: if you don’t see any changes, you may need to add !important clause before the semicolon to force these styles to override other definitions
Example:
.tile .title { font-size: 2.5em !important; }
Okay. thanks a lot. i will work with these to see what I get. I have some non-themed dashes.
Does anyone know the syntax for the font size of the value on the NUMBER variable tile. It doesn’t seem to be icon.
Thanks.
The starting size is ‘3’, so the following will double the size:
.tile.variable.variable-number .main-content > span { font-size: 6em; }
I added it to the top wiki post too.
I’m not sure I understand the use of adjusting margins.
(More accurately - I am sure I don’t understand it!)
This one?
It’s removing the whitespace around the dashboard.
Here’s a screenshot of that snippet applied:
