You're likely encountering default background colors and styles set by Webflow on components like the navbar and form fields, which override or make simple opacity changes ineffective.
1. Identify What's Actually Styled
- Webflow components like the Navbar and Form Blocks/Inputs often have default background colors (e.g., light gray) set at the element level.
- Changing only opacity (e.g., setting to
0
or low values) doesn't remove the background color—it simply makes the entire element (including children) transparent to some extent, but the background color still renders unless manually changed.
2. Make Navbar Transparent Correctly
- Select the Navbar in the Designer.
- In the Style panel, locate Backgrounds.
- Remove or set the Background color to transparent (click the color swatch and drag the alpha slider to 0 or type
rgba(0, 0, 0, 0)
). - Do not rely solely on opacity—you must explicitly clear the background color.
- For each Form Input, Text Area, Select, etc., select the individual element.
- In the Style panel, look for:
- Background color – Set to transparent as you did for the navbar.
- Border style (often uses a light gray 1px solid border)—either remove or restyle it if needed.
- Be aware that placeholder text may still be visible if opacity is applied blindly; use text color overrides instead if needed.
- Use the browser's DevTools (right-click > Inspect) to confirm which styles are still set.
- Or use Webflow's Preview mode and Style panel to see if styles are being inherited from base classes like All Navbars, All Forms, or are set at the element level.
5. Avoid Using Only Opacity
- Setting opacity to 0 hides the entire element, including children, interaction zones, and text—it’s not the same as making just the background transparent.
- Use transparent backgrounds, removing shadows, borders, and applying custom text colors or placeholder styles directly to get the desired appearance.
Summary
Changing only opacity is not enough—Webflow components like navbar and form fields have default background styles you must explicitly remove. Set background color to transparent, and check for other inherited styles like borders or shadows. This is not a bug, but expected behavior based on Webflow’s default styling.
