CSS Classes

This section describes the DevExtreme CSS classes you can use to define the appearance of an element.

dx-clearfix

Set this class to an element to automatically increase the height of this element if floating child elements overflow the current element box.

Show Example:
AngularJS
Knockout
jQuery

dx-field

Defines the appearance of an element displaying a field-value pair within a dx-fieldset element.

The dx-field field element may include label and value elements intended to display the field name and value respectively. Use the dx-field-label, dx-field-value and dx-field-value-static classes to create label and value elements.

HTML
<div class="dx-field">
    <div class="dx-field-label">Full Name</div>
    <div class="dx-field-value-static">John Smith</div>
</div>

DevExtreme UI widgets include WAI-ARIA markup to support screen readers. If you use a widget within a field value element, associate the widget with the field label to allow a screen reader to properly read the field. For this purpose, specify a unique ID for the field label element and assign this ID to the aria-labeledby attribute of the associated widget as demonstrated below.

HTML
<div class="dx-field">
    <div class="dx-field-label" id="fullnameLabel">Full Name</div>
    <div class="dx-field-value">
        <div aria-labeledby="fullnameLabel" id="fullNameTextBox"></div>
    </div>
</div>
AngularJS
HTML
<div class="dx-field">
    <div class="dx-field-label" id="fullnameLabel">Full Name</div>
    <div class="dx-field-value">
        <div aria-labeledby="fullnameLabel" dx-text-box="{ value: fullName }"></div>
    </div>
</div>
Knockout
HTML
<div class="dx-field">
    <div class="dx-field-label" id="fullnameLabel">Full Name</div>
    <div class="dx-field-value">
        <div aria-labeledby="fullnameLabel" data-bind="dxTextBox: { value: fullName }"></div>
    </div>
</div>
NOTE
The dx-field-label and dx-field-value / dx-field-value-static classes are designed to have the label always be before the value. If you need to swap them around, override the float CSS property of these classes in the following way.
CSS
.dx-field-label {
    float: right;
}
.dx-field-value {
    float: left;
}
.dx-field-value-static {
    float: left;
}

Each fieldset item is displayed within a separate field element, which has the dx-field class. The field element may include label and value elements intended to display the field name and value respectively. Use the dx-field-label, dx-field-value and dx-field-value-static classes to create label and value elements.

dx-icon-IconName

Use this class to add a custom icon to the style sheet used in your application.

The name of this class must include the real name of the icon. For instance, the "myicon" icon must be defined by the "dx-icon-myicon" class.

CSS
.dx-icon-myicon
{
  background-image: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAADgAAAA4CAQAAAACj/
  OVAAAARElEQVRYw+3WKQ4AIAADMPb/R4PHIDgTOr/ULUstZxPgfbAvBAgEAoFAIPAhcPebChAIHIKmDQgEAoFA4E/
  g7JcCrk4DW5xoAVzaKL0AAAAASUVORK5CYII=);
}

As you can see, the icon is added in the Base64 type in the code above. We recommend that you also use this type to reduce the number of requests and the amount of data transferred.

The icons that are added to the stylesheet via this class can be used for DevExtreme widgets like predefined icons from the built-in icon library.
