Description

Add the FontSizePicker component to Storybook as part of #17973.
Added with the following "stories":

  • Default
  • With Slider Control
  • With Disabled Custom Sizes

Note: The last story brought to my attention a bug, which is in the process of being resolved in #18049. Once that is merged the story should look correct.

How has this been tested?

run npm run design-system:dev
Browse to the local Storybook instance
See FontSizePicker component is rendered with various options when selected in left-hand navigation

Types of changes

New feature (non-breaking change which adds functionality)

Hmm, this story is not looking right from a design perspective, is there a step I am missing for importing CSS from somewhere @gziolo? Still pretty new to working with Storybook.

All styles should be included with the following import statement:

import '../build-style/style.css';

I filed an issue that describes very similar issues with the ColorPicker component in #18129. I would expect that it's going to be a case for a few more components. Can you open a follow-up issue?

The "Choose preset" text will be fixed with #18165 which converts the base-control to use VisuallHidden component

Looks good, a couple minor changes and it'll be good to go

Actually, you could use knobs with the value and the fontSizes. This way folks could play with the default font size and all the possible font sizes provided. What do you think? @ItsJonQ will be able to help if that makes sense.

I added the fontSizes to a knob, but the value I left as it was. The default 16 is only used on page load, after which point the state takes over. Since changing a knob doesn't reload the component in storybook, there wouldn't be any point in making the value a knob. Because changing it wouldn't reload the component, and reloading the page would reset it to the initial value. Unless I am mistaken about something? (Which is entirely possible 😄 )

I gave it a spin and you are 100% correct. It isn't entirely what I assumed 🙂

Let's leave it as is. I need to double-check other stories and update those which set the initial state with knobs as it doesn't reload as you pointed out.

Let's merge it as. We will need to have another pass on the existing stories at some point and add some visuals. In this case, it could be helpful to have a text which dynamically changes when a new value is applied.

There are also two issues with the component I discovered while testing:

  1. The selected preset doesn't change to Custom when I pick a random value:

  2. The example which has the custom sizes disabled works only partially, since, in the dropdown, there is still
    an option labeled Custom:
