已安装Bree Regular字体但网站不显示，求助解决方法

Hey there! Let's sort out this font issue together—here are the most common fixes to get your Bree Regular font displaying correctly:

1. Double-check the Font Family Name #

The biggest culprit here is usually using the wrong font name in your CSS. The name you use in font-family needs to match the official font name, not just the filename or a shortened version like "Bree Rg".

To find the correct name:

• On Windows: Go to Control Panel > Fonts, find Bree Regular, right-click > Properties, and check the "Font name" field.
• On Mac: Open Font Book, locate Bree Regular, right-click > Show Font Info, and look for the "Full Name" or "PostScript Name".

Most likely, the correct name is either 'Bree Regular' or just 'Bree'—try both in your CSS:

.font {
  font-family: 'Bree Regular', sans-serif;
}

Adding a fallback font (like sans-serif) ensures text still displays if the custom font fails.

2. Ensure Proper @font-face Declaration #

If you're using the font on a website (not just a local project), you need to properly declare the font with @font-face so browsers can load it. Here's a complete, working example:

@font-face {
  font-family: 'Bree Regular'; /* Match this to what you use in font-family */
  src: url('path/to/Bree-Regular.otf') format('opentype');
  font-weight: normal;
  font-style: normal;
}

.font {
  font-family: 'Bree Regular', sans-serif;
}

• Double-check the url() path: Make sure it points to where your .otf file is stored (relative to your CSS file). A typo here will break the font load.
• If you get errors with format('opentype'), try using format('otf') instead—some browsers recognize this shorthand better.

3. Fix the Format("opentype") Error #

If you're seeing an error when adding format("opentype"), here's what to check:

• File path validity: Confirm the font file exists at the path you specified. Use your browser's DevTools (Network tab) to see if the font is failing to load (a 404 error means the path is wrong).
• Corrupted font file: Sometimes downloaded fonts get corrupted. Try re-downloading the Bree Regular font and replacing the file in your project.
• Browser compatibility: While most modern browsers support OpenType, ensure you're not testing on an outdated browser version (like IE8 or older).

4. Local Font vs. Web Font #

If you only installed the font locally on your computer, it will only work for you—not for other visitors to your site. To make it work for everyone, you must include the font file in your project and use @font-face to serve it, as shown in step 2.
