Changing Font Size on Mobile Only

Site URL: https://www.diallekt.com

On my website homepage, it says "Our online FLUENCY ACCELERATOR™ course teaches you a method for becoming fluent in any language" - which is currently in Paragraph 1 font (1.2rem). However, I want the font in that specific text block to be slightly smaller (1rem) on mobile, while staying the same size (1.2rem) on desktop. Is there any way to do that?

Thank you so much.

Thank you so much.

The following Css code could achieve this

@media only screen and (max-width: 767px) {
  #block-yui_3_17_2_1_1652321734868_4479 strong{
    font-size: 1rem;
  }
}

Let me know how it goes

@bangank36 it worked! Thank you so much for helping me on this.
