autocomplete='off' type='checkbox' 
<?php if(in_array(array('no_kursi_order' => 'A1'), $kursi))

试试这个

<div class="container">
<input name='kursi[]' value='A1' id='A1' onclick='cer(this)' 
autocomplete='off' type='checkbox' 
<?php if(in_array(array('no_kursi_order' => 'A1'), $kursi))
<!-- How to add style background-color here --> 
-          {echo "disabled checked";
+          {echo "disabled checked style="background-color: red;"";

<label class='checkmark' for='A1'>A1</label>
</div>
