Hello,

I am using an extended fruity twentythree theme with a custom background and I am having trouble styling the end page. I have encountered a problem with background to the welcome page and end page, since by default it has none. I have managed to add white background to the welcome page which works great by adding this line of code to the custom.css file:
.survey-welcome {
    background: white;
    padding: 1em;
}

However I haven't been able to find the right name for the end page. I have tried to add some variations of the code along with what i added to to welcome page to the custom.css, but none have worked for me:
.survey-end/complete/completed/submit/submitcomlpete/endpage

Is there some name of the endpage that I am missing? Or am I missing something else? 

Thanks a lot for the reply!
