MudEngine Part 8: Inventory & Chat

Step 8 / 10
◀ PrevNext ▶

CSS Additions

The new UI needs styles for the floating player list, chat panel, command input, inventory panel, and room items. The floating player list uses position: fixed so it stays glued to the right edge of the viewport regardless of scrolling.

Append these styles to assets/main.css. Keep all existing styles from previous parts.

/* Shift content left so the fixed panel doesn't overlap */
.game-layout {
    margin-right: 250px;
}
💡 Layout strategy

The floating player list uses position: fixed to stay pinned to the right edge. This means it's outside the normal document flow — it doesn't push other elements.

We add margin-right: 250px to .game-layout to keep the main content visible without overlapping the panel. The panel width is 240px (width: 240px), so 250px of margin gives a 10px gap.

The bottom row uses display: flex to arrange chat, controls, and inventory side by side. Each panel has its own background and scroll behavior, so the page doesn't grow vertically beyond the viewport.
