### Font sizes

Define your font sizes. By default Bricks Boilerplate uses fluid values. There are many sites where you can calculate and generate fluid sizes, e.g. this one: <https://geary.co/clamp-calculator/>

{% hint style="info" %}
Just Bricks version calculates REM to PX as it is, meaning 1rem = 16px. It doesnt change the root font size to 62.5% but keep it as it is => 100%.
{% endhint %}

**Brand colors**

Change this to match your project style. You can use this tool to generate shades and tints for your brand color: <https://noeldelgado.github.io/shadowlord/> or pick one from Radix colors: <https://www.radix-ui.com/colors>

Main primary color is --bt-brand-9, so you should set your main shade for that css variable.
