-- Use `footer_links` parameter instead of removed `show_api` in gr.Blocks()
+- 🚨 **BREAKING CHANGE**: `theme`, `css`, `js`, `head` parameters moved from `gr.Blocks()` to `demo.launch()`
+- 🚨 **gr.Blocks() has NO parameters** - use `with gr.Blocks() as demo:` (no args!)
+- 🚨 **ALL app-level params go in demo.launch()**: `theme=`, `css=`, `footer_links=`, etc.
+- Use `footer_links` parameter in `demo.launch()` (NOT show_api)
 - Use `api_visibility` instead of `api_name` in event listeners
 - Use modern Gradio 6 component syntax (check documentation below)

+## Gradio 6 Themes (Modern UI Design):
+
+Gradio 6 provides powerful theming capabilities. Use themes to create beautiful, professional interfaces:
+
+**Built-in Themes:**
+```python
+import gradio as gr
+
+# Use predefined themes in launch() - Gradio 6 syntax
+with gr.Blocks() as demo:
+    gr.Textbox(label="Input")
+
+demo.launch(theme=gr.themes.Soft())  # Soft, rounded design
+# demo.launch(theme=gr.themes.Glass())  # Modern glass morphism
+# demo.launch(theme=gr.themes.Monochrome())  # Clean monochrome
+# demo.launch(theme=gr.themes.Base())  # Default base theme
+```
+
+**Custom Themes:**
+```python
+import gradio as gr
+
+# Create custom theme
+custom_theme = gr.themes.Soft(
+    primary_hue="blue",
+    secondary_hue="indigo",
+    neutral_hue="slate",
+    font=gr.themes.GoogleFont("Inter"),
+    text_size="lg",
+    spacing_size="lg",
+    radius_size="md"
+).set(
+    button_primary_background_fill="*primary_600",
+    button_primary_background_fill_hover="*primary_700",
+    block_title_text_weight="600",
+)
+
+with gr.Blocks() as demo:
+    gr.Textbox(label="Input")
+
+demo.launch(theme=custom_theme)  # Apply theme in launch() - Gradio 6!
+```
+
+**Best Practices:**
+- 🚨 **CRITICAL**: In Gradio 6, `theme` goes in `demo.launch()`, NOT in `gr.Blocks()`
+- Use `gr.themes.Soft()` for modern, friendly apps
+- Use `gr.themes.Glass()` for sleek, contemporary designs
+- Customize colors with `primary_hue`, `secondary_hue`, `neutral_hue`
+- Use Google Fonts: `font=gr.themes.GoogleFont("Roboto")`
+- Adjust sizing: `text_size`, `spacing_size`, `radius_size` (sm/md/lg)
+- Fine-tune with `.set()` for specific CSS variables
