Unfortunately, you can't directly increase the height of the Squarespace announcement bar using built-in settings. It's designed to be a subtle notification element at the top of your site. Here's why, along with ways to work around this limitation:

Why Squarespace Limits Announcement Bar Height

• Design Philosophy: Squarespace prioritizes a clean, uncluttered aesthetic. Giant announcement bars can be visually intrusive.

• User Experience: Too-large bars disrupt site navigation and content consumption.

Workarounds and Solutions

1. Strategic Content:

   • Keep it Short: Use concise, impactful text to get your message across without needing more space.

   • Clear CTA: Include a strong call-to-action button that stands out.

   • Color Contrast: Choose a background color contrasting your site design to draw attention without increasing the size.

2. Custom CSS (Limited Control):

   • Example Code:

     CSS
     .sqs-announcement-bar-content {
        font-size: 18px; 
        line-height: 26px;
     }
     
     /* Smaller adjustment for the close button  */
     .sqs-announcement-bar-close:after {
       font-size: 20px; 
       line-height: 20px; 
     }

     • How-To:

       1. Go to Design > Custom CSS

       2. Paste the code above.

       3. Adjust the pixel values for padding to experiment slightly.

   • Limitations: This only increases padding around the content, not the overall bar size dramatically.

3. Alternative Solutions:

   • Pop-Up: Consider a pop-up for important announcements that need to stand out more prominently. Use sparingly to avoid being annoying.

   • Top Section: Dedicate the first section of a key page to the announcement, giving you full design control over its appearance.

Important Note:

Custom CSS solutions may break with Squarespace updates. Always test any code changes thoroughly.
