Size mode for application

You can enable touch mode (bigger theme) for an application by adding .e-bigger class in the ~/wwwroot/css/site.css file and assign to the body element in the ~/Pages/Shared/_Layout.cshtml page.

~/site.css
.e-bigger {
    font-size: x-large;
}

~/_Layout.cshtml
<body class="e-bigger">...</body>

Size mode for a Control

You can enable touch mode (bigger theme) for ASP.NET Core controls by adding .e-bigger class and assign to the div which contains the control.

CSHTML
<div class="e-bigger">
    <ejs-calendar id="calendar"></ejs-calendar>
</div>

<div class="e-bigger">
    <ejs-button id="element" content="Button"></ejs-button>
</div>

<div class="e-bigger">
    <ejs-checkbox id="default" label="Checked" checked="true"></ejs-checkbox>
</div>

<style>
    .e-bigger {
