Appearance and Styling

Slider widget looks sleek and enriched with good UI appearance. It is included with both metro (flat) theme and gradient theme support. Totally 17 built-in themes are provided including six flat themes and six gradient themes, material, office-365, bootstrap, high-contrast-01, high-contrast-02. The themes include three color variations such as “Azure”, “Lime” and “Saffron”. The themes supported by the Slider widgets are as follows,

  • flat-azure
  • flat-azure-dark
  • flat-lime
  • flat-lime-dark
  • flat-saffron
  • flat-saffron-dark
  • gradient-azure

  • gradient-saffron
  • gradient-saffron-dark
  • high-contrast-01
  • high-contrast-02
  • material

In order to apply different themes, you can refer the “ej.web.all.min.css” file from the corresponding theme folders. This file is a combination of two style sheets “ej.widgets.core.min.css” and “ej.theme.min.css”. Instead of including “ej.web.all.min.css” file you can also refer the “ej.widgets.core.min.css” and “ej.theme.min.css” files separately.

CSS Class

When you want to display the Slider widget in a different style based on the appearance of your application, you can use this cssClass property to apply custom theme for the Slider. Specify a class name as the value for cssClass property. The specified class is added to the wrapper of the Slider widget. Now, you can easily override the styles of the Slider widget by accessing the styles from the root level (using the cssClass specified).

The following steps explains you on how to configure the Slider with custom theme using the cssClass property. Here, a class name “purple” is specified for the cssClass.

  • html
  • <div>Range Slider</div>
    
    <ej-slider [values]="values" [sliderType]="range" width="500" [cssClass]="cssclass"></ej-slider>
  • html
  • <script>
     import { Component, ViewEncapsulation } from '@angular/core';
    
    @Component({
      selector: 'ej-app',
      templateUrl: './slider.component.html',
      styleUrls: ['./slider.component.css'],
      encapsulation: ViewEncapsulation.None 
    })
    export class SliderComponent { 
        public values: any = [25,75];
        public range: string ='range'; 
        public cssclass: string = "purple";
        constructor() {
        }
    }
    </script>

    Include the cssClass value before each style of the Slider widget and customize the styles as follows in slider.component.css file.

  • css
  • <style>
       .purple.e-slider.e-widget {
           background-color: burlywood;
           border-color: #bbbcbb;
       }
       .purple.e-tooltip {
           background: none repeat scroll 0 0 violet;
           /* Old browsers */
           border-color: #1b95cf;
           color: white;
       }
       .purple.e-slider .e-handle.e-select {
           background-color: purple;
           border-color: purple;
       }
       .purple.e-slider .e-handle.e-hover {
           background-color: purple;
           border-color: purple;
       }
       .purple.e-slider .e-handle.e-focus {
           box-shadow: 0 0 2px rgba(0, 0, 0, 0.2);
       }
       .purple.e-slider .e-range {
           background: none repeat scroll 0 0 violet;
       /* Old browsers */
       }
       .purple.e-scale .e-tick {
