## 📖 Overview

Themes in `PortProtonQT` allow customizing the UI appearance. Themes are stored under:

- `~/.local/share/PortProtonQT/themes`.

---

## 📁 Creating the Theme Folder

```bash
mkdir -p ~/.local/share/PortProtonQT/themes/my_custom_theme
```

---

## 🎨 Style File (`styles.py`)

Create a `styles.py` in the theme root. It should define variables or functions that return CSS.

**Example:**
```python
def custom_button_style(color1, color2):
    return f"""
    QPushButton {{
        background: qlineargradient(x1:0, y1:0, x2:1, y2:0,
                                    stop:0 {color1}, stop:1 {color2});
    }}
    """
```

## 🎥 Animation configuration

The `GAME_CARD_ANIMATION` dictionary controls all animation parameters for game cards:

```python
GAME_CARD_ANIMATION = {
    # Type of animation when entering or exiting the detail page
    # Possible values: "fade", "slide_left", "slide_right", "slide_up", "slide_down", "bounce"
    # Determines how the detail page appears and disappears
    "detail_page_animation_type": "fade",

    # Border width of the card in idle state (no hover or focus)
    # Affects the thickness of the border around the card when it's not selected
    # Value in pixels
    "default_border_width": 2,

    # Border width on hover
    # Increases the border thickness when the cursor is over the card
    # Value in pixels
    "hover_border_width": 8,

    # Border width on focus (e.g., when selected via keyboard)
    # Increases the border thickness when the card is focused
    # Value in pixels
    "focus_border_width": 12,

    # Minimum border width during pulsing animation
    # Determines the minimum border thickness during the "breathing" animation
    # Value in pixels
    "pulse_min_border_width": 8,

    # Maximum border width during pulsing animation
    # Determines the maximum border thickness during pulsing
    # Value in pixels
    "pulse_max_border_width": 10,

    # Duration of the border thickness animation (e.g., on hover or focus)
    # Affects the speed of transition from one border width to another
    # Value in milliseconds
    "thickness_anim_duration": 300,

    # Duration of one pulsing animation cycle
    # Determines how fast the border "pulses" between min and max values
    # Value in milliseconds
    "pulse_anim_duration": 800,

    # Duration of the gradient rotation animation
    # Affects how fast the gradient border rotates around the card
    # Value in milliseconds
    "gradient_anim_duration": 3000,

    # Starting angle of the gradient (in degrees)
    # Determines the initial rotation point of the gradient at animation start
    "gradient_start_angle": 360,

    # Ending angle of the gradient (in degrees)
    # Determines the final rotation point of the gradient
    # Value 0 means a full 360° rotation
    "gradient_end_angle": 0,

    # Type of card animation on hover or focus
    # Possible values: "gradient", "scale"
    # "gradient" enables a rotating gradient for the border, "scale" enlarges the card
    "card_animation_type": "gradient",

    # Card scale in idle state
    # Determines the base size of the card (1.0 = 100% of original size)
    # Value as a fraction (e.g., 1.0 for normal size)
    "default_scale": 1.0,

    # Card scale on hover
    # Increases the card size on hover
    # Value as a fraction (e.g., 1.1 = 110% of original size)
    "hover_scale": 1.1,

    # Card scale on focus (e.g., when selected via keyboard)
    # Increases the card size on focus
    # Value as a fraction (e.g., 1.05 = 105% of original size)
    "focus_scale": 1.05,

    # Duration of scale animation
    # Affects how fast the card changes size on hover or focus
    # Value in milliseconds
    "scale_anim_duration": 200,

    # Easing curve type for border thickness increase animation (on hover/focus)
    # Affects the "feel" of the animation (e.g., smooth acceleration or deceleration)
    # Possible values: strings corresponding to QEasingCurve.Type (e.g., "OutBack", "InOutQuad")
    "thickness_easing_curve": "OutBack",

    # Easing curve type for border thickness decrease animation (on hover/focus exit)
    # Affects the "feel" of returning to the default border width
    "thickness_easing_curve_out": "InBack",

    # Easing curve type for scale increase animation (on hover/focus)
    # Affects the "feel" of the scaling animation (e.g., with a "bounce" effect)
    # Possible values: strings corresponding to QEasingCurve.Type
    "scale_easing_curve": "OutBack",

    # Easing curve type for scale decrease animation (on hover/focus exit)
    # Affects the "feel" of returning to the original scale
    "scale_easing_curve_out": "InBack",

    # Gradient colors for animated border
    # List of dictionaries, each specifying position (0.0–1.0) and color in hex format
    # Affects the appearance of the border on hover or focus if card_animation_type="gradient"
    "gradient_colors": [
        {"position": 0, "color": "#00fff5"},    # Starting color (cyan)
        {"position": 0.33, "color": "#FF5733"}, # Color at 33% (orange)
        {"position": 0.66, "color": "#9B59B6"}, # Color at 66% (purple)
        {"position": 1, "color": "#00fff5"}     # Ending color (back to cyan)
    ],

    # Duration of fade animation when entering the detail page
    # Affects the speed of page appearance with fade animation
    # Value in milliseconds
    "detail_page_fade_duration": 350,

    # Duration of slide animation when entering the detail page
    # Affects the speed of page sliding animation
    # Value in milliseconds
    "detail_page_slide_duration": 500,

    # Duration of bounce animation when entering the detail page
    # Affects the speed of page "bounce" animation
    # Value in milliseconds
    "detail_page_bounce_duration": 400,

    # Duration of fade animation when exiting the detail page
    # Affects the speed of page disappearance with fade animation
    # Value in milliseconds
    "detail_page_fade_duration_exit": 350,

    # Duration of slide animation when exiting the detail page
    # Affects the speed of page sliding animation
    # Value in milliseconds
    "detail_page_slide_duration_exit": 500,

    # Duration of bounce animation when exiting the detail page
    # Affects the speed of page "compression" animation
    # Value in milliseconds
    "detail_page_bounce_duration_exit": 400,

    # Easing curve type for animations when entering the detail page
    # Applied to slide and bounce animations; affects the "feel" of movement
    # Possible values: strings corresponding to QEasingCurve.Type
    "detail_page_easing_curve": "OutCubic",

    # Easing curve type for animations when exiting the detail page
    # Applied to slide and bounce animations; affects the "feel" of movement
    # Possible values: strings corresponding to QEasingCurve.Type
    "detail_page_easing_curve_exit": "InCubic"
