Customizing Material UI CSS in Angular: A Guide

Question

Customizing Material UI CSS in Angular: A Guide

Recently, while working with the Mat-grid-tile tag, I noticed that it utilizes a css class called .mat-grid-tile-content, which you can see below.

The issue I am encountering is that the content within the mat-grid-tile tag appears centered, rather than following a top-to-bottom alignment.

I discovered that by disabling or changing the align-items property to align-items: flex-start in the CSS snippet provided below using browser dev tools, the desired top-to-bottom layout is achieved.

My question now is, how can I override this specific property? I have read that applying inline styles may not work, and ng::deep is considered bad practice. Any suggestions on how I can modify this to display the data in a top-to-bottom manner would be highly appreciated.

It seems like chat-gpt doesn't have any insights on this matter.

.mat-grid-tile-content {
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    position: absolute;
    display: flex;
    align-items: center;
    justify-content: center;
    height: 100%;
    padding: 0;
    margin: 0;
}

I'm still learning Angular, so your patience and guidance are much appreciated.

Altering Angular Material CSS can be challenging due to encapsulation constraints. For more details on this topic, you can check out the following link: https://material.angular.io/guide/customizing-component-styles.

There is no straightforward way to customize Angular Material styles since they are not meant to be easily modified. However, if you still wish to proceed, there are three potential methods:

Turn off encapsulation: Disabling encapsulation will impact all CSS styling within the component, including elements nested inside other components in your template. More information on this can be found here: https://angular.io/guide/view-encapsulation.
Override the .mat-grid-tile-content class in the style.css file located at the root of your Angular project. Any CSS styles defined there will affect any HTML templates across your project. If changes do not take effect, consider using the !important keyword at the end of the property.
Utilize ::ng-deep (deprecated): Despite being deprecated, some developers still opt for ::ng-deep as a workaround due to the lack of a perfect alternative. Exercise caution, however, as deprecation could result in issues down the line.

To sum up, while it is not recommended to alter Angular Material styles, if you decide to proceed, weigh the potential implications of each method carefully.

To ensure that your CSS has the highest priority, you can implement encapsulation by using ViewEncapsulation.None in the component's TypeScript file.

For example:

TypeScript

Sample (Demo)

By following this approach, you can update the content color without relying on ng-deep. This method is recommended by Angular itself as the correct solution.

When using mat-grid-tile, you have the option to utilize two additional selectors:

<mat-grid-tile-header></mat-grid-tile-header>

<mat-grid-tile-footer></mat-grid-title-footer>

By organizing your data in this way, you can move the content inside mat-grid-tile-header without affecting other implementations. I suggest using the following three styles to solve your problem:

Separate style sheet approach

HTML:

<mat-grid-list cols="4" rowHeight="100px">
  <mat-grid-tile
    *ngFor="let tile of tiles"
    [colspan]="tile.cols"
    [rowspan]="tile.rows"
    [style.background]="tile.color"
  >
    <mat-grid-tile-header> {{tile.text}} </mat-grid-tile-header>
  </mat-grid-tile>
</mat-grid-list>

Local style sheet file contents:

.mat-grid-tile .mat-grid-tile-header {
  align-items: flex-start;
  justify-content: center;
  background: transparent;
}

Single style binding

 <mat-grid-tile-header
  [style.align-items]="'flex-start'"
  [style.justify-content]="'center'"
  [style.background]="'transparent'"
>
  {{tile.text}}
</mat-grid-tile-header>

An attribute directive - NgStyle. Make sure to import Common Module

    <mat-grid-tile-header
          [ngStyle]="{'align-items': 'flex-start', 'justify-content': 'center', 'background': 'transparent'}"
        >{{tile.text}}
    </mat-grid-tile-header>
