How can I customize the appearance of the MP4 to MP3 Converter?

The MP4 to MP3 Converter template uses Tailwind CSS for styling. You can customize the appearance by modifying the styles.css file. For example, to change the background color of the body and the header, you can update the following CSS variables:

css :root { --bg-color: #1e3a8a; /* Change this to your desired background color */ --header-bg: #1e40af; /* Change this to your desired header background color */ }

You can also modify other styles directly in the CSS file or by adding Tailwind utility classes to the HTML elements in the template files.

How can I add error handling for file size limits in the MP4 to MP3 Converter?

To add file size limit checking, you can modify the convert_route function in the routes.py file. Here's an example of how to implement a 50MB file size limit:

```python @app.route("/convert", methods=["POST"]) def convert_route(): if 'mp4_file' not in request.files: return render_template("home.html", error="No file part")

   file = request.files['mp4_file']
   if file.filename == '':
       return render_template("home.html", error="No selected file")

   # Check file size
   if file.content_length > 50 * 1024 * 1024:  # 50MB in bytes
       return render_template("home.html", error="File size exceeds 50MB limit")

   if file and file.filename.endswith('.mp4'):
       # Existing conversion code...
   else:
       return render_template("home.html", error="Invalid file format. Please upload an MP4 file.")

```

This code checks the file size before processing and returns an error message if the file exceeds the 50MB limit. Remember to also update the HTML template to display this new error message.
