Hide Title & Subtitle when I click on Gallery Block? (Custom CSS)

Site URL: http://ryanmariehelfant.com/selected-films

When I click on one of my gallery thumbnails, it takes me to my gallery video. Above the video, I see my Title & Subtitle. Is there Custom CSS to hide the Title & Subtitle from being above the gallery video? I only want it to appear on the Page with all my thumbnails, but I don't want it to appear when I click on my gallery thumbnails!

Add to Home > Design > Custom CSS

.project-layout-left-sidebar #projectPages .project .project-meta {
    display: none !important;
    visibility: hidden !important;
}
