Basics of row and column

    <span class="row">
       <div class="col">.col</div>
       <div class="col">.col</div>  
    </span>

rows are specified with class row and columns with class name col

Even spacing of columns

    <span class="row">
       <div class="col">.col</div>
       <div class="col">.col</div>  
       <div class="col">.col</div>  
       <div class="col">.col</div>  
       <div class="col">.col</div>  
    </span>

In above example all columns take up 20% of space depending on the screen width of the device. i.e., 100/5 = 20. There are 5 columns.

Explicit column spacing

    <span class="row">
       <div class="col col-50">.col-50</div>
       <div class="col">.col</div>  
       <div class="col">.col</div>  
    </span>

Here the first column takes 50% of the width and the other 2 columns share the width equally i.e., 25% each.

Column offset

    <span class="row">
       <div class="col col-offset-25 col-25">.col-25</div>
       <div class="col col-25">.col-25</div>  
       <div class="col col-25">.col-25</div>  
    </span>

Above code leaves 25% offset at the beginning, then a column of width 25% followed by 2 more columns of 25% width.

Column positioning

    <span class="row">
       <div class="col col-top">.col-top</div>
       <div class="col col-center">.col-center</div>  
       <div class="col col-bottom">.col-bottom</div>  
       <div class="col">
        1 <br />2 <br />3 <br />4
       </div>
    </span>

The first column aligns itself to the top, the second one to the center and the last one to the bottom.

Row positioning – Going vertical

    <span class="row row-center">
       <div class="col">.col</div>
       <div class="col">.col</div>  
       <div class="col">.col</div>  
       <div class="col">
        1 <br />2 <br />3 <br />4
       </div>
    </span>

row-center class makes the row align itself to the center, row-top makes it align itself to the top and row-bottom makes row to align itself to the bottom.

responsive grid

    <span class="row responsive-sm">
       <div class="col">.col</div>
       <div class="col">.col</div>  
       <div class="col">.col</div>  
    </span>

You can see its effect only on real devices. You must test it with real devices having different screen size.

responsive-sm for devices smaller than landscape.
responsive-md for devices smaller portrait tablet.
responsive-lg for devices smaller than landscape tablet.

UI
Using this simple ionic grid system we can make our applications User Interface to suit our applications needs.

Further ..
For further configuration, each class uses a Sass variable that can be changed to your liking. There’s also a responsive-grid-break mixin you can use to create your own grid classes.
