About this tool

Generates CSS code for curved corners by allowing users to visually manipulate border radii. The tool provides controls that let developers adjust the curvature amount independently for each of the four corners of an element. Users select units such as pixels, percentages, or ems while seeing real-time updates on a preview panel. This interactive interface ensures precise control over corner shaping, making it easy to visualize how different radius values affect web design elements before writing any code. Developers building modern user interfaces and web components find this utility essential for achieving polished aesthetics. Instead of manually testing multiple CSS declarations in a text editor, designers can experiment quickly with various combinations of rounding on the fly.

HTML Entity Encoder3 options

Developers and web designers often need to convert special characters into their corresponding HTML entities to ensure proper rendering across different browsers. HTML Entity Encoder provides a reliable method to transform sensitive characters—such as angle brackets, ampersands, and quotes—into standardized code that prevents browsers from misinterpreting them as functional HTML tags. This process is essential for anyone looking to display raw code snippets on a webpage or securely manage user input within a web application. The utility also integrates XSS prevention analysis, offering insights into how specific encoding choices contribute to site security. By substituting potentially malicious characters with safe entities, it helps mitigate the risk of cross-site scripting attacks that target vulnerabilities in data handling. Users can switch between encoding and decoding functions to verify their data or restore entities to their original plaintext format for editing and review.
