Why did my Angle slider disappear?

The angle slider is hidden when you select a Radial gradient, as radial gradients expand circularly from the center.

What resolution are the downloaded gradient images?

The Ultimate Guide to the Gradient Generator

The Gradient Generator is a dual-purpose design tool built for both web developers and visual artists. It allows you to visually construct complex, multi-stop gradients and instantly export them as native CSS code for your websites or as high-resolution (2560px) PNG images for your design projects, social media backgrounds, or video assets.

Who Will Use This?

Front-End Developers: Stop guessing CSS syntax! Visually construct linear, radial, or conic gradients and copy the exact background: CSS rule with a single click.
UI/UX Designers: Quickly generate beautiful gradient assets in precise aspect ratios (like 16:9 or 9:16) for mockups without opening heavy design software.
Video Editors & Creators: Export ultra high-resolution gradient backgrounds to use as backdrops for text, quotes, or green-screen replacements in your videos.

How to Create & Export Gradients

Choose Your Canvas Ratio: Select 16:9 (Desktop/Widescreen), 9:16 (Stories/Reels/Shorts), 1:1 (Instagram Post), or 4:5 (Portrait Post). This ensures your live preview and PNG export match your target medium perfectly.
Select the Gradient Style:
- Linear: A smooth transition along a straight line.
- Radial: A circular transition radiating from the center.
- Conic: A sweeping circular transition rotating around a center point.
Set the Angle: If you are using a Linear or Conic gradient, use the slider to adjust the rotation angle from 0° to 360°.
Add and Adjust Color Stops: You can add up to 6 distinct color stops. For each stop, click the color circle to pick a hue, and drag the horizontal slider to change its position (0% to 100%) in the gradient flow.
Export Your Work:
- For Web: Click COPY CSS CODE (or simply click the black code box) to copy the exact CSS property.
- For Graphics/Video: Click DOWNLOAD IMAGE (PNG) to save a beautiful 2560px high-resolution image tailored to your chosen aspect ratio.

Common Problems & Tips

Here are some quick tips to get the best results from the Gradient Generator:

Why did my Angle slider disappear? The angle slider is automatically hidden when you select a "Radial" gradient, because radial gradients transition outward in a circle from the center, making an angle setting irrelevant.
Hard Stop Effects: To create sharp lines or "hard stops" between colors instead of a smooth blend, add two different colors and set their position sliders to the exact same percentage (e.g., set both to 50%).
High-Resolution Exports: No matter how small the preview looks on your screen, clicking "Download Image" always renders a massive 2560px base image, ensuring it looks perfectly crisp on 4K monitors or in high-end video projects.

PRACTICAL EXAMPLES & WORKFLOWS

THE COMPLETE GUIDE: GRADIENT GENERATOR ( IMAGE + CSS CODE)

1. WHAT IS THE GRADIENT GENERATOR?
The Gradient Generator is a professional design utility built specifically for video editors, graphic designers, and web developers. Whether you are building websites or designing video assets, this tool provides a highly visual, drag-and-drop interface. You can immediately generate pristine CSS code for your web builds or download high-resolution PNG backgrounds for video thumbnails, social media posts, and branding assets.

2. WHY YOU NEED THIS (KEY BENEFITS)
• Dual-Purpose Output: This is one of the only tools that instantly generates both raw CSS code for web developers and high-resolution PNG image files for graphic designers and editors simultaneously.
• Visual Precision: Fine-tune linear, radial, and conic gradients with exact percentage stops and precise rotational angles while watching the preview update at 60fps.
• Time Saver: Manually writing complex CSS gradient syntax (especially conic gradients) is notoriously difficult and error-prone. This tool writes perfectly vendor-prefixed, clean CSS code for you to copy in one click.
• Zero Compression: When exporting images, the tool generates a massive, lossless PNG (up to 2560px), ensuring no pixelation or banding when used in professional design and editing projects.

3. WHO IS THIS BUILT FOR?
• Video Editors & YouTubers: Generate vibrant, uncompressed backgrounds for video thumbnails (16:9 ratio) and drop your cutout portraits or text on top of them in Premiere or Photoshop.
• Front-End Developers: Quickly generate complex CSS background codes for building websites and modern web applications without having to look up syntax.
• Graphic & UI/UX Designers: Prototype color schemes and aesthetic brand backgrounds rapidly for app interfaces and mockups.
• Social Media Managers: Create perfect 1:1 (Square) or 4:5 (Portrait) gradient backdrops for Instagram quotes, carousel posts, or Twitter graphics.

4. COMPONENT & FEATURE BREAKDOWN

A. Gradient Setup
• Frame Ratio: Force the preview window into exact industry standard aspect ratios: 16:9 (YouTube/Desktop), 9:16 (TikTok/Shorts), 1:1 (Instagram Square), or 4:5 (Instagram Portrait).
• Gradient Style: Instantly toggle between Linear (straight lines), Radial (circular from the center), and Conic (sweeping around a central point).
• Rotation Angle: A smooth slider that allows you to spin Linear and Conic gradients 360 degrees to find the perfect directional lighting.

B. Color Stops
• Multi-Stop Support: Add up to 6 distinct color stops to create rich, complex color transitions (like iridescent holographics or sunset fades).
• Precision Sliders: Use the slider next to each color to dictate exactly where the color begins to blend (from 0% to 100%).
• Native Color Picker: Click the color circle to open your system's native HEX/RGB color picker for pixel-perfect brand matching.

C. Export Result
• CSS Code Box: A dedicated terminal window that automatically writes the exact CSS property required to replicate your gradient on the web.
• Copy CSS Button: One-click clipboard copy for developers.
• Download Image (PNG): Instantly renders a massive, ultra-high-resolution (2560px) PNG file of your gradient, perfectly cropped to your chosen Frame Ratio.

5. STEP-BY-STEP WORKFLOW GUIDE
Step 1: Set Your Canvas
Look at the "Gradient Setup" panel. If you are making a YouTube thumbnail background, select "16:9". If you are making CSS for a website button, keep it at default. Choose your gradient type (Linear is best for modern UI, Radial for spotlights).

Step 2: Build Your Colors
Go to the "Color Stops" section. Click "+ Add Color Stop" if you want more than two colors. Click the color circles to pick your brand colors, and drag the sliders left or right to control how harshly or softly the colors blend into each other.

Step 3: Export Your Assets
If you are a developer, click "Copy CSS Code" and paste it directly into your stylesheet. If you are a designer, click "Download Image (PNG)" to save a massive, high-quality background file straight to your computer.

6. PRO-TIPS & LIMITATIONS
• Hard Lines: To create a "hard" line between two colors instead of a soft blend, place two different colors at the exact same percentage point (e.g., Color 1 at 50%, Color 2 at 50%).
• Conic Compatibility: While Conic gradients are fully supported in modern CSS and will export perfectly to PNG, very old web browsers may fall back to solid colors.
• Smooth Blends: For the smoothest transitions, try to pick colors that are relatively close on the color wheel (Analogous colors), or use a dark and light variant of the same hue.
