Summary

Remove the legacy <meta http-equiv="X-UA-Compatible" content="IE=edge"> tag from Astro fixtures and examples where it is no longer needed.

Background & Motivation

X-UA-Compatible was used for Internet Explorer compatibility mode, but modern browsers ignore it and Internet Explorer is no longer a supported target for typical Astro usage. Keeping this tag in fixtures and examples adds unnecessary boilerplate and makes the HTML slightly larger and harder to maintain.

This proposal aims to simplify Astro’s markup examples and test fixtures by removing a legacy tag that does not provide value for modern web output.

Goals

Remove X-UA-Compatible from Astro fixtures and examples where it is only serving legacy IE behavior.
Reduce repeated boilerplate in HTML examples and test fixtures.
Keep Astro’s default/example markup aligned with modern browser behavior.
Make head markup simpler and easier to maintain.

Example

<html>
  <head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width,initial-scale=1" />
  </head>
