@resonate/tachyons
A fork of the tachyons-custom
css library used to style templates and components for Resonate branded user interfaces, such as stream2own
.
See configuration below for usage with postcss.
Install
npm install --save @resonate/tachyons
Add to a monorepo package
lerna add @resonate/tachyons --scope "@resonate/app"
How to use
We can import @resonate/tachyons
into our front-end application using sheetify
. The library's CSS classes then become globally available.
Here is an example of how we would import @resonate/tachyons
into a choo
application:
const choo = require('choo')
const html = require('choo/html')
const css = require('sheetify')
css('@resonate/tachyons')
const app = choo()
app.route('/', (state, emit) => {
return html`
<div class="bg-pink pa3 h-100 w-100">
Hello world
</div>
`
})
app.mount('#app')
Using the library
Using @resonate/tachyons
is the same as using the standard tachyons
library. For introductory documentation as to how use tachyons
, you can head to the tachyons website.
@resonate/tachyons
modifies a handful of pre-existing CSS classes from tachyons
, and also adds several more:
Colors
@resonate/tachyons
changes 7 color classes. Their class names are the same, but their values have been updated:
Typography
Font sizing with @resonate/tachyons
works somewhat differently than it does with regular tachyons
.
Using tachyons
, developers can specify which font size to use at different breakpoints using class modifiers. For example, if we wanted to style a <div>
to render font size f1
on desktop, f2
on tablets, and f3
on mobile, we would write:
<div class="f1-l f2-m f3">
Hello world
</div>
However, with @resonate/tachyons
developers only have to specify one class name to adhere to Resonate's typography design system. That element's font-size
will then change automatically over different breakpoints:
<div class="f2">
Hello world
</div>
Overriding fonts
On rare occasions when you need to override a particular font-size
, the currently suggested method is to create a sheetify
class that would override the font-size
variable at a chosen breakpoint. Note that because @resonate/tachyons
' font classes also include letter-spacing
properties, you may also need to override this property too.
Spacing
@resonate/tachyons
still uses the same padding and margin classes as tachyons
(eg. .ma0
, .mr2
, .pa4
), however the variables used to calculate each class have changed.
@resonate/tachyons
uses the following spacing variables:
--spacing-extra-small: 0.533rem;
--spacing-small: 0.867rem;
--spacing-medium: 2.200rem;
--spacing-large: 3.667rem;
--spacing-extra-large: 5.867rem;
--spacing-extra-extra-large: 9.533rem;
--spacing-extra-extra-extra-large: 15.400rem;
(Important! These variables may be subject to change.)
Fills
@resonate/tachyons
adds several classes that allow developers to set a fill
property on template elements. Using the color variables from earlier, here's a list of available fill
classes:
.fill-black { fill: var(--black); }
.fill-near-black { fill: var(--near-black); }
.fill-dark-gray { fill: var(--dark-gray); }
.fill-mid-gray { fill: var(--mid-gray); }
.fill-gray { fill: var(--gray); }
.fill-light-gray { fill: var--light-gray); }
.fill-white { fill: var(--white); }
Theming
Apply dark
or light
theme for backgrounds, text colors, border colors, and fills.
To achieve this, we added dark
and light
as a modifier for these classes.
Take a look at src/utilities/_skins-color-scheme.css
and src/utilities/_fills-color-scheme.css
.fill-black--dark { fill: var(--black); }
.fill-near-black--dark { fill: var(--near-black); }
.fill-dark-gray--dark { fill: var(--dark-gray); }
.fill-mid-gray--dark { fill: var(--mid-gray); }
.fill-gray--dark { fill: var(--gray); }
.fill-light-gray--dark { fill: var--light-gray); }
.fill-white--dark { fill: var(--white); }
By using @media (prefers-color-scheme: dark)
we can handle browsers with support for dark/light color schemes.
On newer versions of Firefox and Safari from macOs 10.14.3, dark
or light
theme is automatically set instead of default light
.
