Why This Matters
Media, iframe, and Files is part of the practical frontend foundation. You will use it when building forms, tables, dashboards, reports, and API-connected screens for ASP.NET Core or full-stack projects.
HTML can show images, play audio/video, embed external pages, upload files, and provide downloads.
The Problem
Beginners often copy HTML code without understanding what each line does. In a real School Management System, that leads to pages that are hard to maintain, hard to debug, or confusing for users. This lesson focuses on understanding the pattern first, then applying it in small practical examples.

iframe
Use iframe to embed another page, map, video, or report.
<iframe
src="https://www.google.com/maps"
title="School location map"

height="400">
</iframe>
Always add a meaningful title.
File Upload
<form action="/api/students/documents" method="POST" enctype="multipart/form-data">
<label for="photo">Student Photo</label>
<input type="file" id="photo" name="photo" accept="image/*">
<button type="submit">Upload</button>
</form>
Use enctype="multipart/form-data" when uploading files.
