Change the size and color of post title below the masthead?

[lorenhoboy]

I was earlier advised the following code would change Titles on both Pages and Posts, but it only changes Page Titles.
/Change the size and color of page & post title below the masthead. Add black background with radius corners and padding/
.h-landmark.entry-title span {
font-size: 75%;
display: inline-block;
border-radius: 25px;
background: #000;
padding: 5px 25px 10px;
color: #ff6400 !important;
}
How do I change Blog/Posts text as was done for the Page Title?

Hello Loren,

Thanks for writing in!

The post titles were not in landmark header. If it situated within the post contents. To change it, you will need this code:

.single-post .entry-title{
    display: inline-block;
    border-radius: 25px;
    background: #000;
    padding: 5px 25px 10px;
    color: #ff6400 !important;
}

We would love to know if this has worked for you. Thank you.
