Hi,

You can add the following properties in the web-app.properties file to affects viewport meta tag of Vaadin HTML pages:

cuba.web.useDeviceWidthForViewport = true
cuba.web.pageInitialScale = 1

The result will be as follows:

<meta name="viewport" content="width=device-width, initial-scale=1">

There is no property to define maximum-scale, but you can extend CubaBootstrapListener and provide viewport meta tag there.

import com.haulmont.cuba.web.sys.CubaBootstrapListener;
import com.vaadin.server.BootstrapPageResponse;
import org.jsoup.nodes.Element;

public class CustomBootstrapListener extends CubaBootstrapListener {

    @Override
    public void modifyBootstrapPage(BootstrapPageResponse response) {
        Element head = response.getDocument().getElementsByTag("head").get(0);

        includeMetaViewport("width=device-width, initial-scale=1, maximum-scale=1", response, head);
    }
}

Register a new bean in web-spring.xml:

<bean id="cuba_BootstrapListener"
      class="com.haulmont.sampler.web.CustomBootstrapListener"/>
