Grid

Simple grid for flexible layouts.

Uses flexbox to produce flexible easy to use classes for rows and columns.

There are 2 versions of Grid. A modern version and one with -prefixes- for better browser support.

How to use

Install

bower install wiz-grid

or

npm install grid-css --save

Basic grid

.grid {
  display: flex;
}
.cell {
  flex: 1;
  box-sizing: border-box;
}

Example

<div class="grid">
  <div class="cell">first</div>
  <div class="cell">second</div>
  <div class="cell">third</div>
</div>

This will create a simple flexible row of cells.

-------------------------------------
| first    | second     | third     |
-------------------------------------

Nesting

You can nest grids inside cells with relative ease...

Example

<div class="grid">
  <div class="cell">
    <div class="grid">
      <div class="cell">first</div>
      <div class="cell">second</div>
    </div>
    <div class="grid">
      <div class="cell">third</div>
      <div class="cell">fourth</div>
    </div>
  </div>
  <div class="cell">fifth</div>
</div>

Little complicated to explain. This is what it should produce:

-------------------------------------
| first      | second     | fifth   |
--------------------------|         |
| third      | fourth     |         |
-------------------------------------

Widths

.cell-width-20 {
  flex: 0 0 20%;
}

Example

<div class="grid">
  <div class="cell cell-width-20">first</div>
  <div class="cell">second</div>
  <div class="cell">third</div>
</div>

In this example the first cell is 20% the width of the grid, the other two share the remaining space equally.

-------------------------------------
| first        | second   | third   |
-------------------------------------

Offsets

.cell-offset-20 {
  margin-left: 20%;
}

Example

<div class="grid">
  <div class="cell cell-width-10">first</div>
  <div class="cell cell-width-10 cell-offset-80">second</div>
</div>

Adding cell-offset-80 will add a margin-left: 80% to the cell, pushing it right.

---------                  ----------
| first |                  | second |
---------                  ----------

Wrapping

.grid-wrap {
  flex-wrap: wrap;
}

Example

Here we have 2 cells, 50% and 66.6666% wide, but the grid is only 100% wide...

<div class="grid">
  <div class="cell cell-width-50">first</div>
  <div class="cell cell-width-66">second</div>
</div>

this means the cells are now in control and have broken out of their confinment!

<div class="grid grid-wrap">
  <div class="cell cell-width-50">first</div>
  <div class="cell cell-width-66">second</div>
</div>

Adding grid-wrap will push the second cell down under the first cell.

-------------------
| first           |
-------------------
-----------------------
| second              |
-----------------------

Why not just make this default behaviour? Leaving this option to the developer provides more flexibility.

Vertical alignment

/* All cells */
.grid-top {
  align-items: flex-start;
}
.grid-center {
  align-items: center;
}
.grid-bottom {
  align-items: flex-end;
}

/* Individual cells */
.cell-top {
  align-self: flex-start;
}
.cell-center {
  align-self: center;
}
.cell-bottom {
  align-self: flex-end;
}

Example

<div class="grid grid-bottom">
  <div class="cell cell-top">first</div>
  <div class="cell cell-center">second</div>
  <div class="cell">third</div> <!-- grid-bottom pushes this to the bottom -->
  <div class="cell">fourth
    <br>fourth
    <br>fourth
    <br>fourth
    <br>fourth
    <br>
  </div>
</div>

Notice there are two vertical aligment rules being applied to this grid. A grid wide rule of grid-bottom that pushes everything to the bottom, and per cell alignment rules of cell-top and cell-center that vertically align the cells to the top and center of the grid respectively.

------------                        -------------
| first    |                        | fourth    |
------------                        |           |
                                    | fourth    |
            -------------           |           |
            | second    |           | fourth    |
            -------------           |           |
                                    | fourth    |
                        -------------           |
                        | third     | fourth    |
                        -------------------------

Responsiveness

@media (min-width: 24em) and (max-width: 48em) {
  .grid-medium-fit > .cell:not([class*="cell-width"]) {
    flex: 1;
  }
  .grid-medium-full {
    flex-wrap: wrap;
  }
  .grid-medium-full > .cell {
    flex: 0 0 100%;
    margin-left: 0;
  }
}

Example

Let's make this grid thing respond to different screen sizes...

<div class="grid grid-small-full grid-medium-fit grid-large-full">
  <div class="cell cell-top">first</div>
  <div class="cell cell-center">second</div>
  <div class="cell">third</div> <!-- grid-bottom pushes this to bottom -->
  <div class="cell">fourth
    <br>fourth
    <br>fourth
    <br>fourth
    <br>fourth
    <br>
  </div>
</div>

• .grid-small-full this rule makes the cells full width but only when the screen is small
• .grid-medium-fit makes the cells share the space, but only for medium screens
• .grid-large-full turns it all into columns again

Utility classes

There are some handy "make visible when small" and "hide when large" rules for you to play with.

.visible-small {
  display: none;
}
.hidden-medium {
  display: none;
}
.hidden-large {
  display: none;
}
