If you have a personal plan, you'll want to add a code block to the page, or if you have a higher plan, you can go to your Design panel and click on Custom CSS.
For the code block, try:
<style>
// Remove Underlines From Links //
a {
border-bottom: none!important;
}
<style>
If you put it in Custom CSS, you don't need the opening and closing style tags (which indicate that the code is CSS, for the code block). You can directly just put in:
// Remove Underlines From Links //
a {
border-bottom: none!important;
}
Note if used in Custom CSS, this will remove underlines from all links on your website. If you want it only to apply to your home page, you'll want to use a code block, or put your url here so folks can help you target that page only.
