 <h6 [matMenuTriggerFor]="dashboarditems">
  <mat-icon style="transform: scale(1.2);">line_weight</mat-icon> </h6>

  <mat-menu  class="mat-menu-panel"  [overlapTrigger]="true" #dashboarditems="matMenu"><br/><br/>
<a  routerLink='/home' routerLinkActive='active'>
<span matTooltip="HOME"><mat-icon style="color:lightgreen;">home</mat-icon></span></a><br/><br/><br/>

</div>


<style>

.background {
/* Remember to use the other versions for IE 10 and older browsers! */
display: flex;
min-height: 100%;
font-family: 'verdana', sans-serif;
color: #fff;
height:100vh;
background: #222222;
background: #16222A; /* fallback for old browsers */
background: -webkit-linear-gradient(to top, #16222A , #3A6073); /* Chrome 10-25, Safari 5.1-6 */
background: linear-gradient(to top, #16222A , #3A6073); /* W3C, IE 10+/ Edge, Firefox 16+, Chrome 26+, Opera 12+, Safari 7+ */
}

p{
font-size:20px;
font-weight:bold;
font-family: 'verdana', sans-serif;
margin:3px;
}

h6{
    font-size:12px;
    font-weight:bold;
    font-family: 'verdana', sans-serif;
}

.mat-raised-button{
    text-align:left;
    border-radius:10px;
    font-size:11px;
    font-weight:bold;
    font-family: 'verdana', sans-serif;
    color:white;
    background:transparent;
}

.mat-icon {
    transform: scale(1.5);
}

.matTooltip{
    font-size:11px;
    font-weight:bold;
    font-family: 'verdana', sans-serif;
    }

.mat-menu-panel {
    min-width: 35px;
    max-width: 280px;
    overflow: auto;
    -webkit-overflow-scrolling: touch;
    max-height: calc(100vh - 48px);
    border-radius: 2px;
    outline: 0;
    background: transparent;
    padding-left: 10px;
}
</style>

This is my output

Here I am trying to change the background color for the mat-menu container to transparent and also set some other styles.

When i change in console its getting reflected back as shown below

But when i applied the same changes in my code , the styles are not being applied.

I also tries explicitly adding class="mat-menu-panel" in the component and the div in which i added the mat-menu.

But still the styles are not being applied..

can anybody please help me to fix this styling..

please access my sample code here.. https://stackblitz.com/edit/angular-mat-formfield-flex-layout-vc3fsj?file=app%2Fapp.component.html

@Heena not sure how to phrase this differently, that link does not work — bugs
Any custom styling to mat-menu is best done in the theme .scss file. In your style.scss file you already put rules for body, try adding the mat-menu styles there. A good resource to check out is this one blog.thoughtram.io/angular/2017/05/23/… — arsanyf

You can't have styles in your html template. You need to put them in separate stylesheet. Once you've done that, it may not work for styling material components, because of angular's default style encapsulation.

You can

set the styles to global styles.css file

Style.css

.mat-menu-panel {
min-width: 35px;

use the ng-deep combinator

Put your styles in component specific stylesheet

Component.css

:host ::ng-deep  .mat-menu-panel {
min-width: 35px;
/* ...*/

Change the component' s encapsulation

Put your styles in component specific stylesheet and change the component' s code

Component.ts

@Component({
//...
 encapsulation: ViewEncapsulation.None 
 })

With that last one, styles will leak to entire app (like in global style sheet)
