How to Reduce Header Height in Shopify Dawn Theme

Introduction

Shopify’s Dawn theme has revolutionized the way we design and customize online stores. With the introduction of sections on all pages, not just the homepage, store owners and developers now have more flexibility than ever before. However, one common challenge many face is adjusting the header height to better suit their brand’s aesthetic. In this guide, we’ll explore how to reduce the header height in the Dawn theme, providing you with step-by-step instructions and additional tips to perfect your store’s appearance.

Understanding the Dawn Theme Structure

The Importance of Headers in E-commerce

Headers play a crucial role in e-commerce websites. They’re often the first element visitors see and can significantly impact user experience and navigation. A well-designed header can enhance brand recognition and improve site usability.

Dawn Theme’s Unique Features

The Dawn theme stands out due to its modular structure and performance optimization. Unlike previous Shopify themes, Dawn utilizes sections throughout the entire site, offering unprecedented customization options.

Locating Header Elements in Dawn

Before making changes, it’s essential to understand where header elements are located within the Dawn theme structure. Unlike some older themes, Dawn doesn’t always place header code in predictable files like theme.liquid or header.liquid.

Reducing Header Height: The Solution

The Most Effective Method

After extensive testing, the most reliable method to reduce the header height in the Dawn theme involves modifying the CSS. Here’s the step-by-step process:

1. Go to your Shopify admin panel and navigate to “Online Store” > “Themes”.
2. Find your active Dawn theme and click “Edit code”.
3. In the Assets folder, locate and open the file named “base.css”.
4. Scroll to the bottom of the file and paste the following code:

@media screen and (min-width: 990px) {
  .header__heading-logo {
    width: 40% !important;
  }
  .header {
    padding-top: 0rem !important;
    padding-bottom: 0rem !important;
  }
}

5. Save the changes.

This code targets desktop views (screens wider than 990px) and adjusts the logo width and header padding to create a more compact header.

Understanding the CSS Modifications

Logo Width Adjustment

The .header__heading-logo class controls the logo size. By setting it to 40% width, we ensure it doesn’t dominate the header space.

Header Padding Reduction

Setting both padding-top and padding-bottom to 0rem removes any extra space above and below the header content, effectively reducing its height.

Fine-Tuning the Results

While the provided CSS offers a good starting point, you may need to adjust values to achieve the perfect look for your store. Experiment with different percentages for logo width and padding values to find the ideal balance.

Additional Customization Options

Adjusting for Different Screen Sizes

To ensure your header looks great on all devices, consider adding media queries for different screen sizes. For example:

@media screen and (max-width: 989px) {
  .header {
    padding-top: 0.5rem !important;
    padding-bottom: 0.5rem !important;
  }
}

This code will apply slightly different padding for mobile and tablet views.

Modifying Logo Size

If you find that adjusting the CSS isn’t enough, you can also change the logo size directly in the Shopify theme customizer:

1. Go to “Online Store” > “Themes” > “Customize”.
2. Navigate to the header section.
3. Look for logo size options and adjust as needed.

Altering Banner Height

For those looking to reduce the height of banner images as well, you can add the following CSS to your base.css file:

@media screen and (min-width: 750px) {
  .banner__media {
    height: -webkit-fill-available !important;
  }
}

This code ensures that banner images don’t take up excessive vertical space on larger screens.

Troubleshooting Common Issues

Logo Appears Too Small

If your logo appears too small after reducing the header height, try increasing the width percentage in the CSS. For example:

.header__heading-logo {
  width: 60% !important;
}

Header Elements Overlap

In case header elements start to overlap after height reduction, you may need to adjust the positioning of individual elements. Consider using flexbox or grid layouts to maintain proper alignment.

Mobile View Distortions

Always test your changes on multiple devices. If the mobile view looks distorted, create separate CSS rules for smaller screen sizes to ensure a consistent experience across all devices.

Optimizing Performance After Modifications

Minifying Custom CSS

After making changes to your CSS, consider minifying the code to improve load times. You can use online tools or Shopify apps designed for code optimization.

Leveraging Browser Caching

Ensure your Shopify store is set up to leverage browser caching. This will help returning visitors load your modified header more quickly.

Monitoring Site Speed

Use tools like Google PageSpeed Insights to monitor your site’s performance after making header modifications. This will help ensure that your customizations don’t negatively impact load times.

By following this guide, you should be able to successfully reduce the header height in your Shopify Dawn theme, creating a sleeker and more customized look for your online store. Remember to always test your changes across different devices and browsers to ensure a consistent and professional appearance for all your visitors.
