Demo

• Writeup

Setup

Simply fill in/adjust the relevant variables.

• $responsive is used to turn csswizardry-grids’ responsive features on and off. csswizardry-grids is designed primarily for responsive builds but can also be used on non-responsive projects just as easily. Setting this to false will simply prevent Sass generating your palm etc modifiers.
• $gutter controls how much space there is between columns.
• $mobile-first controls whether you would like unclassed grid items to initially adopt `width:100%;. This means that you won’t need to add a class to force a grid item to take up the full width of its container.
• $use-silent-classes tells csswizardry-grids whether to go ahead and compile solid, traditional classes (e.g. .one-whole) or to create Sass ‘silent’ classes which only compile to CSS once explictly called.
• $lap-start and $desk-start tell csswizardry-grids when to fire particular media queries to service those particular sizes. Note that csswizardry-grids works out the ends of any other breakpoints by using these numbers.

Usage

csswizardry-grids is incredibly simple to implement, its classes are all human-readable and follow the same pattern.

Patterns

csswizardry-grids’ classes are based on a modified BEM syntax.

• .grid is a Block
• .grid__item is an Element
• .grid--rev is a Modifier

Classes include your breakpoint namespaces (e.g. .palm--one-half, .desk--two-thirds and so on); your push and pull classes (.push--one-third, .pull--desk--one-quarter and so on); your regular classes (.one-tenth, .three-quarters etc).

Knowing these patterns will allow you to create hundreds of different combinations. A few examples:

/**
* Sets an item to be one half across all breakpoints.
*/
.one-half{}
/**
* Pushes an item one third of the way to the right across all breakpoints.
*/
.push--one-third{}
/**
* Sets an item to be ten twelfths wide only at the desk breakpoint.
*/
.desk--ten-twelthfs{}
/**
* Pulls an item one half of the way to the left only at the palm breakpoint.
*/
.pull--palm--one-half{}

Classes in markup

If you are using traditional classes then an example, basic usage might look like this:

<div class="grid">
<div class="grid__item lap--one-half desk--two-thirds">
...
</div><!--
--><div class="grid__item lap--one-half desk--one-third">
...
</div>
</div>

It’s as simple as that!

Note the empty HTML comments. These are to remove whitespace caused by using inline-block. Prior to v1.1 this was tackled by using some [letter|word]-spacing trickery, however Chrome 25 introduced a change which meant this method now broke csswizardry-grids.

If you’d rather not use HTML comments to remove the whitespace then you can set the $use-markup-fix variable to false; this invokes a CSS hack that cannot be guaranteed. Always take care to check things over if using this method.

If you need to use csswizardry-grids with a CMS, or data coming out of a loop, you will need to format your template something a little like this: codepad.viper-7.com/MdpMjx

Sass’ silent classes

If you are using silent classes ($use-silent-classes: true;) then your HTML might look like this:

<div class="page">
<div class="content">
...
</div><!--
--><div class="sub-content">
...
</div>
</div>

…and your Sass, something like this:

.page{
@extend %grid;
}
.content,
.sub-content{
@extend %grid__item;
@extend %one-whole;
@extend %lap--one-half;
}
.content{
@extend %desk--two-thirds;
}
.sub-content{
@extend %desk--one-third;
}

Reversed grids (.grid--rev{})

csswizardry-grids has the option to reverse a set of grids; this means that the order you write your source and the order it renders are total opposites, for example:

<div class="grid grid--rev">
<div class="main-content grid__item two-thirds">
I appear first in the markup, but render second in the page.
</div><!--
--><div class="sub-content grid__item one-third">
I appear second in the markup, but render first in the page.
</div>
</div>

This is handy if you want to lay out your page a certain way visually but it would be advantageous to order the source differently, for example to aid accessibility (getting a screenreader to read more important content first).

Gutterless grids (.grid--full{})

It may be desirable at times to have no gutter between your grid items; with csswizardry-grids this is as simple as:

<div class="grid grid--full">
<div class="grid__item one-half">
Look, ma! No gutter!
</div><!--
--><div class="grid__item one-half">
Look, ma! No gutter!
</div>
</div>

Right-aligned grids (.grid--right{})

Keep grids in their correct order, but have them flush right instead of left:

<div class="grid grid--right">
<div class="grid__item one-quarter">
I render first but start in the middle of the page.
</div><!--
--><div class="grid__item one-quarter">
I render second and appear at the very right edge of the page.
</div>
</div>

Centred grids (.grid--center{})

You can centrally align your grids by simply using the .grid--center modifier:

<div class="grid grid--center">
<div class="grid__item one-half">
I’m in the middle!
</div>
</div>

Vertically aligned grids (.grid--[middle|bottom]{})

You can vertically align your grids to each other by simply using the .grid--[middle|bottom] modifiers:

<div class="grid grid--middle">
<div class="grid__item one-half">
I’m in the middle!
</div>
<div class="grid__item one-half">
I’m in the middle!
</div>
</div>

Different sized grids (.grid--[narrow|wide]{})

You can quickly alter the gutter size of your grids to half (.grid--narrow) or double (.grid--wide) by using the relevant modifiers.

<div class="grid grid--narrow">
<div class="grid__item one-half">
I’m a narrow-guttered grid.
</div>
<div class="grid__item one-half">
I’m a narrow-guttered grid.
</div>
</div>

Help and questions

If you have any trouble setting csswizardry-grids up, or would like some help using and implementing it (or any questions about how it works) then please feel free to fire me a tweet or open an issue.

csswizardry-grids’ Sass can look a little daunting, but it’s doing quite a lot of work behind the scenes to make it as simple as possible when it comes to implementation.
