Inside of your business app, navigate to Settings->Profile->Company Description.

The custom company profile code will be placed within the 'Company Description' text box. This box currently supports HTML and most (not all) inline CSS elements. 

Please note: To avoid pixelation, any image assets used within the right hand 'company description' field should render a minimum width of 312px and a max size of 5MB per image/gif.

How to Create HTML / CSS Elements:

Button Code:

<center><a href="https://business.trustpilot.com/" target="_blank" title="Let's Get Started" style="background-color: #04da8d; border: solid; border-color: #111111; border-width: 2px; width:85%; margin-bottom: 25px; border-radius: 5px; display: inline-block; padding: 20px; cursor: pointer;" rel="nofollow noopener noreferrer"><div style="margin-top: 2px;"><span style="color: #111111; font-size: 17px; font-weight: bold;">Let's Get Started</span></div></a></center>

HTML Elements

• <center> aligns the button to the middle of the profile.
• <div> is an HTML container element.
• <span> is an alternate container element for specification. 
• <a href> inserts a clickable link.
• target="_blank" opens the link in a new tab.
• title assigns a title to the button element.
• rel="nofollow noopener noreferrer" insures we are in line with Google's best practices by not including a follow rule. This element is put in place automatically and is not adjustable.

CSS Elements:

• background-color dictates the color of the button.
• border determines the type of border around the button.
• border-color determines the color of the border element.
• border-width is the width of the border in pixels.
• border-radius controls how rounded the corners of the button element are. 
• width is the width of the entire button element.
• margin represents the outside space of the element itself.
• padding represents the inner space surrounding the element.
• display controls how the button is layered amongst the other elements on the page. This should be set to inline-block. 
• font-size dictates the character size.
• font-weight dictates whether the text should be bolded.
