Web View

Type-safe HTML and CSS with intuitive layout and composable styles. Inspired by Tailwindcss and Elm-UI

Write Haskell instead of CSS

Type-safe utility functions to generate styled HTML.

myPage = col (gap 10) $ do
  el (bold . fontSize 32) "My page"
  button (border 1) "Click Me"

Leverage the full power of Haskell functions for reuse, instead of relying on CSS.

header = bold
h1 = header . fontSize 32
h2 = header . fontSize 24
page = gap 10

myPage = col page $ do
  el h1 "My Page"
  ...

This approach is inspired by Tailwindcss' Utility Classes

Intuitive Layouts

Easily create layouts with row, col, grow, and space

holygrail :: View c ()
holygrail = layout id $ do
  row section "Top Bar"
  row grow $ do
    col section "Left Sidebar"
    col (section . grow) "Main Content"
    col section "Right Sidebar"
  row section "Bottom Bar"
  where section = 'border' 1

Embedded CSS

Views track which styles are used in any child node, and automatically embed all CSS when rendered.

>>> renderText $ el bold "Hello"

<style type='text/css'>.bold { font-weight:bold }</style>
<div class='bold'>Hello</div>

Stateful Styles

We can apply styles when certain states apply. For example, to change the background on hover:

button (bg Primary . hover (bg PrimaryLight)) "Hover Me"

Media states allow us to create responsive designs

el (width 100 . media (MinWidth 800) (width 400))
  "Big if window > 800"
