我们可以使用下面的CSS,我们还需要结合我之前的答案Append kendo popup of the kendo-colorpicker to the 'component'中提供的修复
:host ::ng-deep .k-coloreditor-reset kendo-icon-wrapper{
display: none !important;
}
:host ::ng-deep .k-coloreditor-reset {
width: 75px;
position: relative;
}
:host ::ng-deep .k-coloreditor-reset::before {
content: 'Reset All';
position: absolute;
left: 10px;
top:5px;
height: 30px;
width: 50px;
z-index: 300000000;
opacity: 1;
background-color: transparent;
}
