Remove Featured Image/Meta in Blog Post

I’ve read through the forums and have found css code to remove the image in my blog post page, but to no avail. I’ve tried the following below.

Am I missing something? Can someone please advise on how to remove both the featured images as well as the pencil icons (shows when no featured images in not selected) on my blog posts.

thanks in advance.

#top .fullsize .template-blog .blog-meta, #top .fullsize .template-blog .post-meta-infos {
display: none !important;
}

.single .blog-meta {
    display: none !important;
}
