Hi @cqulihui, This is possible at the column level. You would need to know the column id of the 3 x 3 table. If you want to accomplish something as shown in the screenshot attached, you can enter the code under Look and Feel>Style>Custom CSS. To mention, this code is not specific to a particular matrix question. The below settings would apply to all matrix questions. td.c4 { background-color:#90EE90; } td.c5{ background-color:yellow; } td.c6{ background-color:#FA8072; } label.q-radio.q-checked{ background-color:black !important; } !

Thanks very much for your help! @jainshubham If I get it right, after I add this code into Look&Feel-->Style, the background color of all the tables will be changed. I just want to change one Multiple Choice question. How can I do this? And I have been looking for the column id. I failed to find it. Where can I find the ids? Thanks a lot!

Paste the following code in the js(OnReady) of the matrix question jQuery("#"+this.questionId+" td.c4").css("background","grey");

Hi @Shashi, Thanks for your help. I have tried your code. But it doesn't work. I use a Multiple Choice question, not a matrix question. I am not sure whether the question type is the reason that the code doesn't work. Thanks again.
