How can I adjust the weight of a custom font in my theme?

I uploaded a custom font to my theme but for some headings and subheadings it appears to be bold (when it should not be).

Could someone give me the code to remove the heavyweight font and make it the original (see subheading weight in the screenshot below)?

Thanks

@kindredpeople ,

h1.feature-header.align-left.cc-fade-in-up.cc-animate-init.feature-header--visible.-in.cc-animate-complete, h2.line-1.cc-fade-in-up.cc-animate-init.-in.cc-animate-complete {
    font-weight: normal;
}

Add this css at the bottom of Online Store->Theme->Edit code->Assets->style.scss.liquid

This hasn’t worked yet… is there an alternative code I could try?

Also I would like to remove the heavy weight font for all these too so maybe you could add that to the code? Thank you @oscprofessional
