Example: Adding a Border

To add a border to the Angular Material text area field, we can use the following CSS style:

.mat-form-field-appearance-outline .mat-input-element {
border: 1px solid #ccc;
}

The above CSS uses the .mat-form-field-appearance-outline class selector to select the Angular Material text area field and adds a 1-pixel solid border using the border property.

To apply this style to a specific Angular Material text area field, add a class name to the field in your HTML code, and then add that class name to the above CSS styles.

For example, if we have an Angular Material textarea field and want to add a border to it, we can add the class name my-textarea-field in the HTML code and then use that class name in the CSS style:

<mat-form-field class="my-textarea-field"> 
<textarea matInput></textarea> 
</mat-form-field> 

.my-textarea-field .mat-input-element { 
border: 1px solid #ccc; 
} 

In this way, we have successfully added a border to the specified Angular Material textarea field.

Custom Border Styles

In addition to simply adding a solid border, we can customize the border style of Angular Material text area fields as needed. Here are some examples:

Adding a Dashed Border

To add a dashed border, we can use the CSS border-style property and set it to dashed or dotted.

.my-textarea-field .mat-input-element { 
border: 1px dashed #ccc; 
} 

Or

.my-textarea-field .mat-input-element {
border: 1px dotted #ccc; 
} 

Adding a Shadow Border

To add a shadow border, we can use the CSS box-shadow property and provide it with an appropriate value.

.my-textarea-field .mat-input-element {
border: none; 
box-shadow: 0 0 5px #ccc; 
} 

This will create a border with a 5-pixel shadow.

Modifying Border Color and Width

To modify the border color and width, we can use the CSS border-color and border-width properties.

.my-textarea-field .mat-input-element {
border-color: red;
border-width: 2px;
}

This will create a red border with a width of 2 pixels.

Rounded Border

To create a rounded border, we can use the CSS border-radius property and provide it with an appropriate value.

.my-textarea-field .mat-input-element {
border-radius: 5px;
}

This will create a border with a 5-pixel corner radius.
