  In the above image, you can see for the first icon, some background color is coming while hovering.</p>
  
  <p>I tried</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.sidemenuitm {
    padding: 10px 5px;
    cursor: pointer;
    text-align: center;
  }
  
  .lineheight {
    line-height: 13px;
  }
  
  .btn-change {
    border-right: #b41414 3px solid;
  }
  
  .selectedmenu {
    background-color: #fafafa;
    color: black;
    border-left: solid rgb(214, 208, 208) 1px;
    border-top: solid rgb(214, 208, 208) 1px;
    border-bottom: solid rgb(214, 208, 208) 1px;
  }
  
  .backupicon {
    width: 85px;
    white-space: normal;
    font-size: 12px;
    line-height: 1.5;
    display: flex;
    justify-content: center;
  }
  
  button:hover {
    background-color: transparent;
    text-decoration: none;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div *ngIf="element.id=='3'" class="sidemenuitm lineheight" [routerLink]="element.url" routerLinkActive="selectedmenu btn-change" [matTooltip]="menuname ? element.tooltip : ''" matTooltipPosition="right" [matTooltipClass]="'tooltipwidth'"&gt;
    &lt;button mat-button [disabled]="is_accessible" class="backupicon" (click)="selectcomp(i)"&gt;
      &lt;mat-icon class="material-icons-outlined"&gt;{{element.iconname}}&lt;/mat-icon&gt;
      &lt;div *ngIf="menuname"&gt;{{element.name}}&lt;/div&gt;
    &lt;/button&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
