How can I style a newsletter form in Webflow with custom CSS, specifically to have the submit button inside the input field?

To style a newsletter form in Webflow with a submit button inside the input field, you can use a combination of Webflow's built-in styling options and custom CSS. Here's a step-by-step guide:

1. Add a Form Block to your Webflow project by dragging and dropping it onto your desired page.

2. Customize the form by adding the necessary fields, like an email input field.

3. Select the submit button and style it as desired using Webflow's Style Panel. You can customize the button's size, background color, text color, font, and more.

4. To place the submit button inside the input field, you'll need to use custom CSS. Here's an example CSS snippet that you can add to the project:

```css
/* Styles the form container to appear as inline */
.form-container {
display: inline-flex;
align-items: center;
}

/* Adds padding to the input field */
.input-field {
padding-right: 80px; /* Adjust the value as needed based on your submit button size */
}

/* Positions the submit button absolutely */
.submit-button {
position: absolute;
right: 0;
}

/* Adjusts the submit button size and appearance */
.submit-button input[type="submit"] {
width: 60px; /* Adjust the value as needed */
height: 40px; /* Adjust the value as needed */
background-color: #000; /* Adjust the color as needed */
color: #fff; /* Adjust the color as needed */
}
```

5. To add the custom CSS to your Webflow project, you can go to the Designer, select the Project Settings (gear icon) in the top-right corner, and then navigate to the Custom Code tab. Place the CSS code within the Head Code section.

By implementing the CSS code snippet above, the form container will display inline, the input field will have extra padding on the right to accommodate the submit button, and the submit button will be positioned absolutely at the right edge. Adjust the values in the CSS to match your desired styling preferences.

Remember to always preview and test your form on different device sizes to ensure it looks and functions as intended.
