Right Navigation Line


Our Right Line Navigation plugin adds an underline that slides in from right to left of your Squarespace site's main navigation. Below you will find a super-simple tutorial that will guide you through the installation and setup of this plugin.

Step 1: Insert the CSS

Insert the following code into your Squarespace site's Custom CSS editor or the Individual Page Header CSS injection (more info below) - the values in bold can be changed to suit your branding and site design. 

Where colour values are added, you can use either of the following:

  • Valid colour name e.g. 'red' or 'yellow'

  • Hex value e.g. #FECB2F

  • RGB(a) value e.g. rgb (255,255,255) or rgba (255,255,255,0.8) - optional opacity value '0.8'

  • HSL(s) value (optional opacity values '0.8') e.g. hsl (0, 0%, 20%) or hsla (0, 0%, 20%, 0.8) - optional opacity value '0.8'

Copy & paste this code:


@media all and (min-width:770px){
header nav a{
  display: inline-block !important; 
  float: left;
header nav a:hover:after{
  transform: scaleX(1);
header nav a:after {
  content: '';
  border-bottom: solid 2px #FECB2F;  
  transform: scaleX(0);  
  transition: transform 250ms ease-in-out;
  z-index: 999;
  transform-origin :100% 50%;

Individual Page Header CSS Injection:

If using this method, be sure to wrap your CSS in <style></style> tags as shown in image 4!



Step 2: Adjust line style (optional)

To change the style of your line, find this code in the Design 'Custom CSS' area and adjust the 2px to the correct thickness and change #FECB2F to the colour code you want to have.

border-bottom: solid 2px #FECB2F;

Step 3: Apply, Save & Refresh! ⚡️
