describe a three-panel HR dashboard built with vanilla HTML and CSS

How would you describe a three-panel HR dashboard built with vanilla HTML and CSS, where a fixed left navigation panel holds employee categories, a scrollable center area fills the remaining space, and a collapsible right panel slides in to show employee details — all laid out using CSS Grid with smooth open/close transitions and a mobile-friendly bottom navigation and slide-up drawer?


~Build a three-panel HR dashboard layout in vanilla HTML and CSS. Carve the screen into a fixed left navigation panel at 240 pixels wide containing employee categories and quick links, a scrollable main content area that fills the remaining width, and a collapsible right detail panel at 320 pixels wide that slides in when an employee record is selected. The left panel and right panel remain fixed while the main area scrolls. Use CSS Grid for the outer layout. Smooth transition when the right panel opens and closes. Mobile: collapse both side panels into a bottom navigation bar and a slide-up drawer.~
