# Webflow Fill vs Cover: What’s the Difference and When to Use Each?

.webp)

**TLDR:**

“Cover” makes background images stretch and crop to fill containers, great for hero sections. “Fill” keeps images fully visible, ideal for icons or logos. Use wisely to avoid visual bugs — and pair with Gapflow to manage form submissions professionally on all layouts.

If you’ve ever set a background image in Webflow, you’ve probably seen the **“Fill”** and **“Cover”** options. These two settings can dramatically affect how your visuals behave across screen sizes — and can make or break the look of a section.

In this article, we’ll break down the **differences between Fill and Cover**, when to use each, and how to design with conversion in mind — especially if your layout includes forms powered by **Gapflow.io**.

## 🖼️ Fill vs Cover: The Core Difference

When setting a **background image** in Webflow (or with CSS in general), you’ll come across two popular `background-size` values:

### 🔹 **Cover**

- The image **covers the entire container**
- Maintains its aspect ratio
- **Cropping may occur** if the image is not the same ratio as the container
- Best for full-width sections or hero backgrounds

### 🔹 **Contain / Fill**

- The image is resized to **fit completely inside** the container
- Maintains its aspect ratio
- **No cropping**, but may leave empty space (padding)
- Best for smaller UI elements like cards or icons

## ✅ When to Use "Cover" in Webflow

Use **Cover** when you want:

- A **hero image** to fully stretch edge-to-edge, even if it crops a little
- To **maintain responsive fluidity** on different screen sizes
- A **clean, modern aesthetic** for full-width sections

💡 **Example Use Case:**

Hero section with background image + overlayed text (e.g. “Contact Us” banner).

## ✅ When to Use "Fill" (aka Contain)

Use **Fill** when:

- You need to display the **entire image without cropping**
- Your image is small or icon-sized
- You care more about **precision than visual immersion**

💡 **Example Use Case:**

Team member profile cards with logo or badge images.

## ⚠️ Common Mistake: Wrong Use of "Cover" for Logos or Icons

Using **Cover** for images that should be displayed in full (like logos) will crop them — often in weird ways. **Use Fill instead.**

## 👩‍💻 Bonus: Why This Matters for UX and Conversion

If your form is placed on top of a background image — especially in a hero section — the wrong sizing (cover/fill) can ruin contrast, responsiveness, or layout clarity. That directly impacts conversion.

Which is where **Gapflow** comes in.
