Hi there 👋

We're going to teach you glamorous by having you edit the guide you're reading 😱

To start, we already have a few components defined for you on the left, so you just have to change their styles to change the way this guide looks and moves!

Basic Styles

Let's start by making the headings on this page look nice. With glamorous, instead of the normal CSS syntax you maybe familiar with, we regular JavaScript objects.

Change the Heading to this:

const Heading = glamorous.h1({
  fontSize: '2.4em',
  marginTop: 10,
  color: '#CC3A4B',
})

Media Queries

Let's make the headings shrink when the view port is narrow (like on mobile devices).

Update the Heading to this:

const Heading = glamorous.h1({
  fontSize: '2.4em',
  marginTop: 10,
  color: '#CC3A4B',
  [mediaQueries.phone]: {
    fontSize: '1.8em',
    backgroundColor: '#CC3A4B',
    color: 'white'
  },
})

Now resize the screen to see how things look

Pseudo classes

Here we have a link. Let's style its pseudo classes like active, visited, and hover.

Update the Link to this:

const Link = glamorous.a({
  ':visited': {
    color: 'darkblue',
  },
  ':hover,:active,:focus': {
    color: 'darkred',
  },
})

Have you visited that link before? 😈

Pseudo Elements

this
is
a
list

Let's change how the list items are rendered here using pseudo elements.

const ListItem = glamorous.li({
  ':before': {
    content: '"💎"',
  }
})

NOTE! It's really common to forget that in CSS, the content property is wrapped in quotes. Even though you're technically doing this because you set content to a string, that string needs to include the quotes that will be inserted into the CSS stylesheet.

Dynamic Styles

You can provide a function as an argument to a glamorousComponentFactory (by the way, that's what glamorous.h1 is called). This function will be called with props.

The CodeBlock component receives the language as a prop. Here's code block that is html:

<html>
<head>
  <title>Hello world!</title>
</head>
<body>
  Hello world!
</body>
</html>

Let's change the styles for html code blocks:

const CodeBlock = glamorous.pre(props => {
  const isHTML = props.language === 'html'
  if (isHTML) {
    return {
      padding: 20,
      backgroundColor: '#0c1e35',
    }
  }
})

Merging Styles

glamorous uses glamor under the hood to generate and insert the CSS you write. One of the cool features of glamor is how composable it is. So with glamorousComponentFactory functions, (like glamorous.pre) you can provide any number of arguments and the styles will be merged. In addition, you can also provide arrays or return arrays for dynamic styles and those will also be merged (where the last one wins in the event of a conflict). Let's try some of that out now:

Update CodeBlock to look like this:

const CodeBlock = glamorous.pre({
  position: 'relative',
  padding: 20,
  ':before': {
    position: 'absolute',
    top: '0',
    opacity: '0.6',
    left: '7px',
    fontSize: '0.8rem',
  },
}, props => {
  const isHTML = props.language === 'html'
  let styles = [
    {
      ':before': {
        content: `"${props.language}"`,
      }
    }
  ]
  if (isHTML) {
    styles.push({
      backgroundColor: '#0c1e35',
    })
  }
  // returning an array here.
  return styles
})

That's it!

That's all we have for now, but if you'd like to help with this guide that'd be super! Please check out the GitHub repo!
