Site URL: http://www.405tutoring.com

Hey, I've got my facebook feed on my home page, thinking it would be nice to put the box in a black outline but I have no idea how to do this (I know nothing about code) and I cant find anything online that works so far!! Any help is appreciated, thank you!

You can add Custom CSS. From within your Squarespace dashboard, go to Design, then Custom CSS.

Enter the following:

iframe[src^="https://www.facebook.com/plugins/page"] {
  border: 2px solid aqua;
}

"2px" means your border will be 2 pixels wide. You can change this.

"solid" means it will be a solid border. You can change this to any of the following

• dotted - Defines a dotted border
• dashed - Defines a dashed border
• solid - Defines a solid border
• double - Defines a double border
• groove - Defines a 3D grooved border. The effect depends on the border-color value
• ridge - Defines a 3D ridged border. The effect depends on the border-color value
• inset - Defines a 3D inset border. The effect depends on the border-color value
• outset - Defines a 3D outset border. The effect depends on the border-color value
• none - Defines no border
• hidden - Defines a hidden border

"aqua" represents the color it will be. You can use any of the 147 named colors, or use a hex color, rgb, hsl,...etc. Here is a link to explain CSS colors.
