Pre-requisites

Working

First of all, we need to enter any YouTube URL of your choice that you want to add video responsively on your web page.
After entering or pasting the URL link >> click on the Generate Embed Code button to generate a responsive YouTube video embed code script. For this, we have used generateEmbedCode(url) JavaScript function to create generated embed code based on URL input by clicking on the Generate Embed Code button.
To copy the generated code we have used the copyEmbedCode() JavaScript function. This helps in copying the generated embed code script to the clipboard by just clicking on the Copy Embed Code button.

Approach

To create and design the YouTube video embed code generator tool, we will be using HTML to structure the tool with a title, input box, and submit button. We will use JavaScript to generate the embed code based on user input, which is the YouTube URL. For CSS styling and visual appearance, we have used responsive CSS code for the best user experience.
