182
+
183

184
+
185
+ ### 🎨 Code Viewer Features
186
+
187
+ **Fullscreen Code Viewer:**
188
+
189
+ - Large, comfortable reading view
190
+ - Full syntax highlighting
191
+ - Copy entire file with one click
192
+ - Quick switch to Artifact mode (for HTML)
193
+
194
+ **✨ Artifacts Preview (HTML Live Preview):**
195
+
196
+ Artifacts are **live HTML previews** - just like Claude.ai! 🎨
197
+
198
+ Instead of just reading HTML code, you can **see it rendered** with full interactivity.
199
+
200
+ **How to use:**
201
+
202
+ 1. Open any `.html` file in the tree
203
+ 2. Click (sparkle icon) in preview panel
204
+ 3. Or click 🔍 (fullscreen) then
205
+
206
+ **Features:**
207
+
208
+ - ✅ Renders HTML in sandboxed iframe (safe!)
209
+ - Auto-loads CSS from `<link>` tags
210
+ - ✅ Auto-loads JS from `<script>` tags
211
+ - ✅ Relative paths resolved automatically
212
+ - Fully interactive (buttons, forms, animations work!)
213
+ - ✅ Refresh with 🔄 button anytime
214
+ - ✅ Switch to code view with 📝 button
215
+
216
+ **Example:**
217
+
218
+ If your `index.html` has:
219
+
220
+ ```html
221
+ <link rel="stylesheet" href="styles.css" />
222
+ <script src="app.js"></script>
223
+ ```
224
+
225
+ Elysia automatically finds and inlines both files! No manual setup needed.
226
+
227
+ **Perfect for:**
228
+
229
+ - 🎨 Previewing static websites
230
+ - 📱 Testing responsive designs
231
+ - 🎮 Checking interactive components
232
+ - 💌 Viewing email templates
233
+ - 📊 Data visualizations
234
+
235
+ **Security:** Runs in sandbox with `allow-scripts allow-same-origin` - isolated from main app.
