The iframe tag is an inline frame in HTML used to embed another webpage within the current page. It has various uses and attributes.

  1. Usage:
  2. Embed the URL in an iframe with a width of 300 pixels and a height of 200 pixels.
  3. Specify the URL of the page to be embedded.
  4. frameborder: Specifies the width of the border, with 0 indicating no border and 1 indicating a border.
  5. Set the width of the iframe.
  6. Set the height of the iframe.
  7. Transparent:
    To make an iframe transparent, you can use CSS styles to set its background color and border style.
  8. Embed a webpage using an iframe element with specific dimensions and styling.
  9. Please make sure to set the background color or border style of the embedded page to transparent or hide if it already has one.
  10. Adaptive height:
    The default height of an iframe is fixed, but it can be made adaptive using JavaScript. First, you need to add the following script in the embedded page:
  12. Next, add an id attribute to the iframe tag and call the resizeIFrame function.
  13. The iframe with the ID “my-iframe” is set to load a URL with a width of 300, and the function resizeIFrame() will be triggered when it finishes loading.
  14. In this way, once the embedded page has finished loading, the iframe will automatically adjust its height to fit the content.

In summary, the iframe tag can be used to embed other pages, and its appearance and behavior can be controlled by setting attributes. Transparency and adaptive height can be achieved using CSS styles and JavaScript.
