I would like to add a thin black horizontal line above my footer. I know I need to go to footer.liquid. and add <hr> at the beginning, but somehow this is not working.
Could somebody help me with more detailed instructions?
Have you tried adding a border-top property to the container?
please Go to Online Store->Theme->Edit code then go to assets/theme.css ->paste below code at the bottom of the file.
border-top: 1px solid #000000;
Please share store URL.
