How to better control CSS class naming in SPFx

CSS is currently not capable of scoping the design only to a component on a web page. It is just possible through different class names for elements on the page. To avoid the inference of same style sheet classes on the same page, SPFx post-fix every class name used in the web parts CSS files. There are also hidden gems that allow you to change this behaviour dynamically as required and sometime the class names shouldn’t be renamed at all cost. Enough about the theory lets take a closer more detailed look.

Scenarios and solutions to use Office UI Fabric – Part 3

In the final part of this series I like to take a look on scenarios, how to use Office UI Fabric efficiently. As mentioned in part two using pure Office UI Fabric might can be a bit difficult sometimes.
Especially when you don’t like to copy and paste the code from the snippet gallery all the time. Personally, I think it is a bit difficult even if you are experienced in using frameworks. There are many things that need to be learned in addition. A thing such as Suit CSS naming conventions, correct class names, components, text sizes, class names of colors, complete HTML structures.

Things you should know about web fonts and font packages

During the last years I’ve intensively used web fonts. Since I published the first blog post on how you use web fonts in SharePoint 2010.
While I just downloaded the web fonts and used the CSS that was included in the font packages I recognized more and more that most of the available web fonts are wrong defined inside the font packages. There are a couple of problems with the definitions of the @fontface that you can avoid creating a cleaner style sheet.

Office 365 Icon font documentation

I’m not quite sure when it happened. During the last twosome of months, Microsoft provides some icon fonts in Office 365.Especially the newly introduced app launcher makes use of icons of this typeface.The content varies from icons, such as the Hamburger menu, arrows, general, UI elements, as considerably as all Microsoft Applications. The files of this font are hosted on the Microsoft CDN so they are ready to use to spice up Apps.

Why to use icon fonts?

Icon fonts provide a couple of benefits. Fonts are scaled better than any image across different screen resolutions and even looks great on high density displays without any loss of quality.
There is another advantage to use this font. By using the same icons as in Office 365 you will be able to provide a consistent user experience.
Microsoft created a while ago some UX Guidelines for Apps in SharePoint, but you won’t find any information on the icons.

How to get access to the icon font of Office 365?

As mentioned earlier CDN is the key. Microsoft provides some centralized assets there. There is only one problem the use of a CDN is mostly undocumented. One general documentation can be found on the MS Technet.
There are several CDN endpoints and in case of SharePoint only one url exist in Office 365 for a long time. This URL is // This url can be accessed via http (port 80) and http’s (port 443).
To make use of the icon font the following code needs to be used in your courses.

You might recognise the path in there that points to “_layout/15 “ which is the current version of SharePoint. The path before the layouts fairly undocumented and might change over time. I try to maintain those urls in future until there is an official documentation available.

Content of the icon font

The font-face definition can be added to the custom style sheet of your app. Again the content of this font is undocumented as well.
This was the reason why I set up a small interactive documentation that use the CDN urls and shows all relevant icons. So you don’t have to search all the 65536 glyphs (or characters).
The guide be found on my newly created lab site under the url
A page that I’m looking forward to maintain in the future and add some additional information and things there.
Following the principles of “Ship or die”. The mobile support is currently beta too. I’m looking forward to provide a superb user experience.
