position radio buttons elements over background image
问题 I have a backgorund image and want to position some radio buttons (the circle of the radio button will be hidden and only the label will appear) just close to the red triangles (as shown here) . How can I do this? Please see my code here input[type="radio"] { display: none; } input[type="radio"]:checked + label { border: 2px solid red; } <img src="http://i.stack.imgur.com/CUTm6.png" alt="Synoptic table" align="center"> <div class="buton"> <input type="radio" name="a" value="a" id="a" />
