Regarding the above css script for the button which has an x as check mark - It works, but I struggle to create a value for each check box. I have tried adding a value to the html part as follow which does not seem to work: <input id="demo_box_2" class="css-checkbox" type="checkbox" checked/> <label for="demo_box_2" value="true" name="demo_lbl_2" value="true" class="css-label">Selected Option</label> Please advise as this does not make sense why it should not be working.
