Why does my HTML file lose CSS and JavaScript on iPad?

Quick answer

This usually happens because the iPad is previewing one file instead of treating the folder as one web project.

Why this happens

CSS, JavaScript, images, and media often depend on relative paths. If the files are separated or previewed outside their project folder, those links can fail.

What you can try

Package the HTML, CSS, JavaScript, and assets as a ZIP, then import the ZIP into an app that keeps the project structure together.

When HTML Pocket helps

HTML Pocket can import a ZIP web project, unpack it into one local project folder, and open the entry HTML with its nearby assets.

• Keep a local history of opened pages

Limits

• It does not repair broken HTML, missing files, or server-only code.
