CSS Grid Template Areas implementation guide Dynamically on Component Re-render in Angular
I'm having an scenario with CSS Grid when using Angular. I have a grid layout defined using template areas in my styles, and I expect it to update dynamically when the component re-renders, but it doesn't seem to reflect the changes. Here's a simplified version of my CSS: ```css .grid-container { display: grid; grid-template-areas: 'header header' 'sidebar main' 'footer footer'; grid-template-rows: auto 1fr auto; grid-template-columns: 200px 1fr; } .header { grid-area: header; } .sidebar { grid-area: sidebar; } .main { grid-area: main; } .footer { grid-area: footer; } ``` In my Angular component, I'm trying to change the layout based on user interactions, which triggers a re-render. However, the CSS does not reflect the new grid template areas; it stays exploring on the initial layout. I used `ngClass` to toggle classes based on the state, and it seems like the grid template is not updating. Here’s an example of my component logic: ```typescript import { Component } from '@angular/core'; @Component({ selector: 'app-dashboard', templateUrl: './dashboard.component.html', }) export class DashboardComponent { isExpanded = false; toggleSidebar() { this.isExpanded = !this.isExpanded; } } ``` And in my template: ```html <div class="grid-container" [ngClass]='{ "expanded": isExpanded }'> <div class="header">Header</div> <div class="sidebar">Sidebar</div> <div class="main">Main Content</div> <div class="footer">Footer</div> </div> ``` The question is that when I toggle `isExpanded`, I expect the grid areas to adjust, but they remain as defined in the original CSS. I've attempted to use `ngStyle` to dynamically set `grid-template-areas` directly in the component, but that didn't work either. Here’s the behavior I’m seeing in the console: `CSS: Grid area 'sidebar' doesn't exist in the template.'` I've checked that the CSS is loaded correctly and nothing else is overriding it. Any insights on how to make CSS Grid dynamically respond to changes in the Angular component?
