# Responsive Properties

Wisej.NET supports a unique system of "responsive properties" in order to enable an application to adapt its UI to the client browser without being limited to CSS media selectors and styles.

Conceptually it's a simple system. Certain properties, usually but not necessarily visual properties (i.e. Visible, Display, Size, Location, etc.) can hold multiple values at the same time and apply the one that matches the current client browser profile.

The only way to assign responsive properties is in the designer.

{% content-ref url="../../concepts/designer" %}
[designer](https://docs.wisej.com/docs/concepts/designer)
{% endcontent-ref %}

All controls expose the [ResponsiveProfiles ](https://docs.wisej.com/api/wisej.web/general/control#responsiveprofiles)collection holding the profiles that contain different responsive property values set at design time. You can use this collection to inspect the client profiles set for the control.
