How to create a border around an iframe?

To create a border around an iframe, you can add the CSS code directly to the iframe element. Here is an example:

1

<iframe src="https://www.example.com" style="border: 1px solid #000;"></iframe>

In this example, the CSS border property is used to add a solid black border of 1 pixel width around the iframe. You can customize the border by changing the width, style, and color values in the border property.

Alternatively, you can also create a CSS class and apply it to the iframe element like this:

<style>
    .iframe-border {
        border: 1px solid #000;
    }
</style>

<iframe src="https://www.example.com" class="iframe-border"></iframe>

This method allows you to easily apply the same border style to multiple iframes by simply adding the class to each one.
