Installation

  1. Just copy/paste the code above somewhere in your CSS file
  2. Create your HTML Layout according the following rules

Rem: The names of the CSS classes have been choosen to allow a perfect compatibility with Bootstrap (you can mix them).

How to use

Beware: it works the opposite of Bootstrap: you define the collapse in the row, NOT in the column!

APG-FLEX offers both the usual collapsing effect and an reverse one: you can chose if you want the collapse to happen under or above the treshold.

  1. Collapse and Reverse Collapse:
    1. COLLAPSE: For each row: indicate at which limit you want the columns to collapse. A row is created by a div with one of the followings classes (example : <div class="arowsm">) :
      • arow : never collapses
      • arowsm: collapses under 576px
      • arowmd: collapses under 768px
      • arowlg: collapses under 992px
      • arowxl: collapses under 1200px
    2. REVERSE COLLAPSE: For each row: indicate at which limit you want the columns to expand. A row is created by a div with one of the followings classes (example : <div class="browsm">) :
      • browsm: collapses over 576px
      • browmd: collapses over 768px
      • browlg: collapses over 992px
      • browxl: collapses over 1200px
  2. Inside the row, add one <div> per column (as much as you want: they will be evenly distributed)

  3. If needed, add to the column div one of the classes flex2 to flex12 to define its respective size (default = flex1; example: <div class="flex2">)

  4. The class acolfinal add padding: .5rem which is useful for the column containing the content

Notes

  1. For Container (max-width: 1070px and centered), add the class "acontainer" to a row (ex: <div class="arow acontainer">)

  2. A div is considered as a Flex Column if and only if it is directly under a arowXX. You can change this behavior by using style (<div style="display: block;">):
    • arow : row
      • div : displayed as Flex (column)
        • div : displayed as Block (default behavior)
      • div : displayed as Flex (column)
      • div style=block : displayed as Block
  3. For nesting, just remember that a column must exist in each row (see example below)

  4. Sizes are respective! (see example below)

  5. flex2...flex12 are optional: suppress or modify them as needed

Simple Example

See the Demo

4 columns, the second one twice the size of the others (so a total size of 5) and containing 4 nested columns:


	<div class="arowsm">            <!-- Row collapsing at 576px -->
	    <div>flex: 1</div>          <!-- Column size 1/5 of the full width -->
	    <div class="flex2">         <!-- Column size 2/5 of the full width -->
	        <div class="arowlg">    <!-- Nested row collapsing at 992px-->
	            <div>flex: 1</div>  <!-- Column size 1/4 of 2/5 = 1/10 of the full width -->
	            <div>               <!-- Column size 1/4 of 2/5 = 1/10 of the full width -->
	                <div>B</div>    <!-- Block (not a column!) -->
	            </div>  
	            <div>flex: 1</div>  <!-- Column size 1/4 of 2/5 = 1/10 of the full width -->
	            <div>flex: 1</div>  <!-- Column size 1/4 of 2/5 = 1/10 of the full width -->
	        </div>
	    </div>
	    <div>flex: 1</div>          <!-- Column size 1/5 of the full width -->
	    <div>flex: 1</div>          <!-- Column size 1/5 of the full width -->
	</div>
