# Advanced

The Advanced section lets you fine-tune your project’s output and local preview behavior. These options are entirely optional, but great if you want a bit more control.

### Site Options

* **Generate Search Engine Sitemap**

  Automatically creates a sitemap.xml file to help search engines index your site.
* **Consolidate CSS Files**

  Combines your project’s CSS into fewer files to help reduce page load time.
* Generate Cache-Busting Links

  Appends unique version strings to assets (like CSS and JS) to ensure browsers always load the latest version.
* **Minify CSS and Javascript**

  Strips unnecessary whitespace and comments to shrink file sizes and improve performance.
* **Anonymize Requests to Third-Party Servers**

  Helps protect your privacy by removing identifiable info from external requests (like Google Fonts or embedded media).

### Default Extension

Sets the file extension used for new pages, typically html, but you can change this to php or others if needed.

### Web Server Port

Configure the local web server used by Elements when previewing your site:

* Auto: Automatically chooses an available port.
* Restart Web Server: Use this if the preview server isn’t running correctly.
* Automatically start web server on document open: Handy if you want preview to be ready as soon as you open a project.
