How to Add CSS in Webflow

Webflow empowers you to build stunning websites visually. However, sometimes you need to dive into code to achieve unique designs or functionalities. This guide will walk you through adding custom CSS and JavaScript to your Webflow website, from basic implementation to advanced techniques.

Understanding Webflow's Style Manager

Webflow provides a powerful visual style manager. Before jumping into custom code, familiarize yourself with it. This tool lets you control various aspects of your website's appearance without writing a single line of code.

Key features:

• Visual styling: Customize fonts, colors, and spacing.
• Class system: Apply reusable styles across multiple elements.
• Responsive controls: Adjust styles for different screen sizes.
• Typography settings: Manage fonts, weights, and alignments.

Adding Custom CSS to Webflow

Sometimes, the visual style manager isn't enough. That's where custom CSS comes in.

How to add custom CSS:

• Navigate to your Project Settings.
• Go to the Custom Code tab.
• Find the Head Code or Footer Code sections.
• Paste your CSS code within <style> tags.

Example:

<style>
.my-custom-class {
    color: blue;
    font-weight: bold;
}
</style>

Webflow Custom CSS and the Class System

Webflow's class system is essential for efficient CSS management. Apply your custom CSS to specific classes to avoid unintended styling changes across your website.

• Webflow class system: Create reusable styles for multiple elements.
• Global vs. local styles: Keep styles organized and prevent conflicts.

Inline CSS vs. External Styles in Webflow

For simple, element-specific styling, you might consider inline CSS. However, for larger projects, adding external CSS via the custom code section is recommended to keep your code organized.

Adding JavaScript to Webflow

JavaScript enables dynamic functionalities, such as animations, interactions, and form validations.

How to add JavaScript:

• Go to your Project Settings → Custom Code tab.
• Paste your JavaScript code within <script> tags.
• For external scripts, use <script src="your-script.js"></script>.

Example:

<script>
console.log("Hello from Webflow!");
</script>

Webflow JavaScript and CSS Integration

Webflow allows seamless integration of JavaScript and CSS. You can use JavaScript to dynamically modify CSS styles or trigger animations based on user interactions.

• Webflow interactions and animations styling: Control animations with JavaScript.
• Modify CSS properties dynamically: Adjust styles based on user behavior.

Webflow Embed Code for Styling and Scripting

The Embed Code element is a powerful tool for adding custom HTML, CSS, and JavaScript directly to specific sections of your website.

How to use embed code for styling:

• Drag the Embed element onto your Webflow page.
• Paste custom CSS inside <style> tags.
• Save and preview the changes.

Webflow Responsive Design with CSS

Ensure your custom CSS is responsive by using media queries to adjust styles for different screen sizes.

Example:

<style>
@media (max-width: 768px) {
    .my-custom-class {
        font-size: 14px;
    }
}
</style>

Troubleshooting Common Issues

Sometimes, CSS and JavaScript may not work as expected. Here’s how to fix common issues:

Webflow Custom Code Editor

While Webflow doesn't have a built-in code editor, using an external editor like VS Code for writing CSS and JavaScript is recommended.

Benefits of an external editor:

• Syntax highlighting: Improves readability.
• Code completion: Helps write cleaner code faster.
• Version control: Keeps track of changes.
