よくある質問
What is a Border Radius Generator?
It is a tool that allows you to visually create rounded corners for HTML elements and automatically generates the corresponding CSS code.
How do I create a circle using this tool?
Set all four corner values (Top-Left, Top-Right, Bottom-Right, Bottom-Left) to the same high value, typically 50% of the element's width or height, or enter '50%' directly.
What does the 'Preview' box do?
The preview box provides a real-time visual representation of how your border radius settings will look on a web element, allowing you to adjust shapes before copying the code.
What is the difference between px and % units?
Pixels (px) are absolute units that create a consistent curve size regardless of element dimensions. Percentages (%) are relative to the element's size; 50% always creates a perfect circle or pill shape, while lower percentages scale with the box.
Can I round only specific corners?
Yes, you can adjust individual handles or input fields for each corner (Top-Left, Top-Right, Bottom-Right, Bottom-Left) independently to create unique shapes.
How do I use the generated CSS?
Click the 'Copy CSS' button to copy the code to your clipboard. Then, paste it into the stylesheet (CSS file) or within a <style> tag in your HTML document for the specific element class or ID.
