Iframely VS CSS Next

• “No code”
  Instead of API calls, an option to use our HTML template and some JavaScript spice.
• JSON
  Only two endpoints to choose from and connect: complete Iframely data or a simple oEmbed connector. Both have the html field for you to embed.
• Cards and URLs previews
  Engage your users with URL preview cards, just like they expect in a modern app. Change cards design easily in your settings.
• React and JavaScript
  React, and other JavaScript runtimes won’t let you run third-party scripts. Iframely fixes this by hosting media in an iFrame instead.
• Responsive embed codes
  Rich media will resize and fit your site’s design on any device, with a correct aspect ratio or a horizontal height.

• Future CSS Features
  CSS Next allows developers to use the latest CSS syntax and features that may not yet be supported by all browsers, enabling progressive enhancement and future-proofing stylesheets.
• Simplified Syntax
  By using future CSS features, developers can write more concise and expressive code, making stylesheets easier to read and maintain.
• Polyfills and Transpilation
  CSS Next automatically provides polyfills and transpiles CSS so that the latest features can be used even in environments that do not yet support them natively.
• Improved Workflow
  With CSS Next, developers can directly utilize tools that help improve styling workflows, such as variables, custom selectors, and media queries, more conveniently.

Possible disadvantages

• Dependency on Tooling
  CSS Next requires a build process for transpilation, which adds complexity and dependencies to project setup and maintenance.
• Potential Performance Overhead
  The polyfills and transpilation process can introduce a performance overhead during development and build times, affecting the speed of initial setup.
• Limited Support for Older Browsers
  While CSS Next helps bring future features to more browsers, it might not fully support significantly older browsers, necessitating additional fallbacks or workarounds.
• Project Activity and Maintenance
  Due to changes in the web development landscape and focus shifts, CSS Next might not be actively maintained, potentially leading developers to use alternatives like PostCSS or native CSS features as they become available.
