CSS Specificity​

I read a lot... and some of what I read is very random, and sometimes that comes in handy. One of the RSS feeds I subscribe to recently had an article on CSS Cascade Layers Vs. BEM Vs. Utility Classes: Specificity Control. Reading it gave me some nicely grounded insight into some things I had sorta figured out but didn't have names for. You dont need to go and read it unless you want a better understanding of how CSS specificity works and different ways of dealing with it (without resorting to just adding !important everywhere).

What does this have to do with ServiceNow theming? Read on and find out...

Yokohama updates​

The Yokohama release is out (and has been for a while, sorry this edition is coming out way late). There are some generally minor, but interesting theme updates

Knowledge 25​

If you are reading this because you subscribed to my RSS feed, and will be at Knowledge, you can find me at the Platform Ask the Expert area Tuesday morning, Wednesday all day, and Thursday Morning. Feel free to reach out to me on the SNDevs slack as well.

This is your chance to hire Eric (Update: I got an internal transfer to a new position at ServiceNow and am no longer looking for something new)​

A few weeks ago I got news that my position at ServiceNow is being eliminated. At this point it is looking very unlikely that I am going to find something internal to transfer to. So I am using Knowledge 25 as the perfect chance to network.

The Pain​

Every quarter or so, ServiceNow released updates to Store apps. This is usually a good thing. The bad part is that you also have to update them in your instance.

Washington DC updates​

This post is really late, sorry.

The big news in the W release is themable illustrations. But there are some issues I found with them.

The setup​

I no longer work with end users very often, but this came across my desk (errr... I got a message on the SNDevs Slack). There was a person in the NextGen program who was working on a project. They had created a custom table and could not get to a next step because half of the fields on the form weren't showing up.

The instructor had checked the usual suspects... The fields were part of the form view, there weren't any UI policies, Data Policies, or Client Scripts hiding them. All the ACLs were passed so that wasn't the issue either.

And... this issue was only happening to a single user account. When the instructor logged in as a different user, they could see the fields just fine.

Any guesses what the problem was?

Here are some of the best properties I have found to set​

There are obviously a lot of properties available. I have found that setting some have much more impact than others. Here are the top ones that I think can make a difference.

How do I make my Themes?​

We have talked about how things are structured and how colors are generated in previous parts. Now we are going to start putting it all together and work out how to use it all in practice.
