How to change this line's color?

is the website drdanieljaredsmith.com & where it says ‘I’d like to change the color of the line below this title…’
Add this to your child theme

.modline-outer {
   border-bottom: 1px solid #78A5B6;(change #78A5B6  to your color)
    border-top: 1px solid #78A5B6;(change #78A5B6 to your color)
    height: 2px; (can be left out in child theme)
    margin-bottom: 18px; (can be left out in child theme)
}
.modline-inner {
    background-color: #78A5B6;(change #78A5B6 to your color)
    height: 2px; (can be left out in child theme)
    width: 25%; (can be left out in child theme)

}

To remove it just add
.modline-outer {
display:none;
}
.modline-inner {
display:none;
]

Thank you!
If I’d got the color right in the first place, I could have saved you the effort. Oh well…

No worries… I like to know users of my themes are ok and things are working. Also thanks to iampng for responding to the topic with the posted code to help lunchbox247 …it makes my job easier ??

Hi! Im trying to change the color of the line but it doesn’t work, I have tried to look for the .modline-outer, think I found the right thing in style.css, I change the color and saved, but nothing appears and the color is still the same gray-blue as it was before.

Do you have any suggestions? My website is: https://aktivaussie.se

Thanks!

Faceup… looks like you found it because it’s green on my end.
