Rock Star Free wordpress theme FEATURE IMAGE TITLE removal

I have the Rock Star Free wordpress theme. I am using pages each with the feature image in order to scroll 4 large full screen images upon initial arrival at the website. The page title is in the middle of the feature image despite all attempts to remove it. I have tried the page title remove plugins as well as the CSS code that includes: .slider-content-wrapper .entry-title{ display: none; } I entered this code in teh custom CSS editor on wordpress. I have tried child themes and I have tried other CSS codes to remove title, but nothing has worked. website is: www.texasremedy.com but I currently have a "under construction" splash page. Please help. I DO NOT want the page title on the pictures that fade into eachother (featured images)
