console.log(output)
Stylesheet properties
Display mode
Elements can have a display of either inline, block, or none:
r.style({
"div": {
display: "block"
}
"span": {
display: "inline" # default
}
"hidden": {
display: "none"
}
})
output = r.render("
<div>This will fill one or more rows.</div>
<span>These</span> <span>will</span> <span>be</span> in the same <span>line.</span>
<hidden>This won't be displayed.</hidden>
")
console.log(output)
Margin
Margins work just like they do in browsers:
r.style({
"li": {
display: "block"
marginTop: "1"
marginRight: "2"
marginBottom: "3"
marginLeft: "4"
# or the shorthand version:
"margin": "1 2 3 4"
},
"highlight": {
display: "inline"
marginLeft: "2"
marginRight: "2"
}
})
r.render("
<ul>
<li>Item <highlgiht>1</highlight></li>
<li>Item <highlgiht>2</highlight></li>
<li>Item <highlgiht>3</highlight></li>
</ul>
")
Padding
See margins above. Paddings work the same way, only inward.
Width and Height
Block elements can have explicit width and height:
r.style({
"box": {
display: "block"
"width": "4"
"height": "2"
}
})
r.render("<box>This is a box and some of its text will be truncated.</box>")
Colors
You can set a custom color and background color for each element:
r.style({
"error": {
color: "black"
background: "red"
}
})
List of colors currently supported are black, red, green, yellow, blue, magenta, cyan, white, grey, bright-red, bright-green, bright-yellow, bright-blue, bright-magenta, bright-cyan, bright-white.
Bullet points
Block elements can have bullet points on their margins. Let's start with an example:
r.style({
"li": {
# To add bullet points to an element, first you
# should make some room for the bullet point by
# giving your element some margin to the left:
marginLeft: "4",
# Now we can add a bullet point to our margin:
bullet: '"-"'
}
})
# The four hyphens are there for visual reference
r.render("
----
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
----
")
And here is the result:
