Custom CSS for the cozy, colorful look

We use the st.markdown with unsafe_allow_html=True to inject CSS for styling.

st.markdown("""

<style> /* Global Background and Font */ body { background-color: #f7f3e8; /* Light linen background */ } .main { background-color: #fefcf3; /* Creamy White "Paper" */ padding: 40px; border-radius: 15px; box-shadow: 0 10px 15px rgba(0, 0, 0, 0.1); font-family: 'Inter', sans-serif; } h1, h2 { font-family: 'Playfair Display', serif; color: #c07e5c; /* Terracotta Accent */ } .stButton>button { border-radius: 12px; font-weight: bold; transition: all 0.2s ease-in-out; } /* Style for the Generate button (Warm Wood Color) */ .stButton:nth-child(1) button { background-color: #a67c52; color: white; border: none; } .stButton:nth-child(1) button:hover { background-color: #8f6a46; } /* Style for the Surprise button (Terracotta Accent Color) */ .stButton:nth-child(2) button { background-color: #c07e5c; color: white; border: none; } .stButton:nth-child(2) button:hover { background-color: #a3694f; } /* Style for the playlist output cards */ .song-list-item { background-color: #a67c521a; /* wood/10 opacity */ padding: 10px; margin-bottom: 5px; border-radius: 8px; border-left: 5px solid #c07e5c; /* Accent border */ } </style>
