A checkbox does not have background color.
But to add the effect, you may wrap each checkbox with a div
that has color:
<div class="evenRow">
<input type="checkbox" />
</div>
<div class="oddRow">
<input type="checkbox" />
</div>
<div class="evenRow">
<input type="checkbox" />
</div>
<div class="oddRow">
<input type="checkbox" />
</div>
