# Razor @ Symbol Fix
|
|
|
|
## 🐛 Issue Found
|
|
|
|
**Error:** "The name 'media' does not exist in the current context"
|
|
|
|
**Location:** Views with CSS `@media` queries
|
|
|
|
## 🔍 Root Cause
|
|
|
|
In Razor views (.cshtml files), the `@` symbol has special meaning - it's used to switch from HTML to C# code. When you write CSS directly in a Razor view, you need to escape `@` symbols in CSS at-rules like `@media`.
|
|
|
|
## ✅ Fix Applied
|
|
|
|
Changed all `@media` to `@@media` in:
|
|
1. ✅ `Views/Home/Index.cshtml` (line 217)
|
|
2. ✅ `Views/Shared/_Layout.cshtml` (line 233)
|
|
|
|
## 📝 The Fix
|
|
|
|
### Before (❌ Causes Error):
|
|
```css
|
|
<style>
|
|
@media (max-width: 768px) {
|
|
/* styles */
|
|
}
|
|
</style>
|
|
```
|
|
|
|
### After (✅ Correct):
|
|
```css
|
|
<style>
|
|
@@media (max-width: 768px) {
|
|
/* styles */
|
|
}
|
|
</style>
|
|
```
|
|
|
|
## 💡 Why Double @@?
|
|
|
|
In Razor syntax:
|
|
- `@` = Switch to C# code
|
|
- `@@` = Escape sequence that outputs a single `@` character
|
|
|
|
So `@@media` in Razor becomes `@media` in the final HTML.
|
|
|
|
## 🎯 Other CSS At-Rules That Need Escaping
|
|
|
|
If you add any of these CSS at-rules in Razor views, remember to escape them:
|
|
|
|
```css
|
|
@@media (min-width: 1024px) { } /* Media queries */
|
|
@@keyframes fadeIn { } /* Animations */
|
|
@@import url('fonts.css'); /* Imports */
|
|
@@font-face { } /* Custom fonts */
|
|
@@supports (display: grid) { } /* Feature queries */
|
|
```
|
|
|
|
## ✅ Best Practice: External CSS
|
|
|
|
To avoid this issue entirely, you can:
|
|
|
|
### Option 1: Use External CSS File (Recommended)
|
|
Create `wwwroot/css/site.css` and link it in your layout:
|
|
```html
|
|
<link rel="stylesheet" href="~/css/site.css" />
|
|
```
|
|
|
|
No need to escape @ symbols in .css files!
|
|
|
|
### Option 2: Keep Inline (Current Approach)
|
|
Just remember to use `@@` for all CSS at-rules.
|
|
|
|
## 🔧 If You See This Error Again
|
|
|
|
1. **Look for CSS at-rules** in your .cshtml file
|
|
2. **Find any `@` symbols** in `<style>` tags
|
|
3. **Double them** → Change `@` to `@@`
|
|
4. **Rebuild** and the error will be gone
|
|
|
|
## 🎯 Quick Test
|
|
|
|
The error is now fixed! When you run the app:
|
|
|
|
```bash
|
|
cd src/PowderCoating.Web
|
|
dotnet run
|
|
```
|
|
|
|
Navigate to `https://localhost:7001` and you should see the beautiful login page without errors!
|
|
|
|
## 📋 Files Fixed
|
|
|
|
1. ✅ `Views/Home/Index.cshtml` - Login page
|
|
2. ✅ `Views/Shared/_Layout.cshtml` - Main layout
|
|
|
|
Both now properly escape the @ symbol in CSS media queries.
