Can I create an opaque text block behind solid text?

Hello, I'm looking for a way to display text over a number of full size images. I have found code to make an opaque block colour but this also affects the text which I would like to remain a solid colour. I would be most grateful for any suggestions - thank you. 

Can you share link to page in screenshot? We can check easier

Thank you very much for your reply!

Remove your code, use this code

#block-9342d5c75a2028eaa58c {
    background: rgba(240,240,240,0.5);
    padding: 50px;
    text-align: center;
}
[data-section-id="5f61e066efbca1309ee6b249"] .content {
    margin: 0 auto;
}

Thank you so much! This is exactly what I have been trying achieve, I'm hugely grateful!
