Remove titles on Sale page images

I would like to remove the title on the store gallery on this page ( See image below)

https://www.partybarnpublications.com/unlimited-use-stock-photography-5-dollars-to-free-stock-photography

The "Sale" is okay to stay, but I just want it to be a grid of images without the title showing.

Can this be done with a code injection? 

Thank you!

Add to Page Header

<style>
.grid-title {
    display: none;
}
</style>

Awesome! Thank you so much for being such a valuable source of help, @tuanphan!  

I do have one other question in regards to the same page and the titles that we removed...

Is it possible to have the title instead appear on the image in the lower left hand corner (either statically, or on a hover) similar to this:

Again, thank you so much for sharing your expertise!

Remove above code & use this code

.grid-title {
    position: absolute;
    bottom: 30px;
    left: 10px;
    font-size: 1.5rem !important;
}

@tuanphan This is perfect! Thank you so much!!
