CSS
Form Runner has a built-in theme for forms. This page documents how you can make changes to that default style.
CSS stands for Cascading Style Sheets, and is the standard technology to add style to web pages and web applications. Orbeon Forms supports custom CSS files which allows you to change your forms' appearance. This assumes that you have some CSS knowledge.
- 1.Place your CSS file(s) under one of the following recommended locations:
WEB-INF/resources/forms/assets
: CSS for all formsWEB-INF/resources/forms/APP/assets
: CSS for app name APPWEB-INF/resources/forms/APP/FORM/assets
: CSS for app name APP and form name FORM
- 2.Define the
oxf.fr.css.custom.uri
property to point to the file(s) you added. The path points to location under theWEB-INF/resources
directory.
<property as="xs:string" name="oxf.fr.css.custom.uri.*.*">
/forms/acme/assets/acme.css
</property>
You can add more than one file, and just separate the paths by whitespace in the property.
Note that the locations suggested are just about how to organize the files for clarity. In addition, if some CSS files apply to specific app or form names, you must specify the app and form name in the property or properties. For example:
<property as="xs:string" name="oxf.fr.css.custom.uri.APP.*">
/forms/APP/assets/my-app.css
</property>
<property as="xs:string" name="oxf.fr.css.custom.uri.APP.FORM">
/forms/APP/assets/my-app.css
/forms/APP/FORM/assets/my-app-and-form.css
</property>
The names
APP
, FORM
, my-app.css
and my-app-and-form.css
are just placeholders for your own app name, form name, and CSS files names.If a specific property is defined for an app/form, such as
oxf.fr.css.custom.uri.APP.FORM
, only that property is considered and other properties defined only for a given app but without a specific form, such as oxf.fr.css.custom.uri.APP.*
, will be ignored. This means that you must repeat references to CSS resources in the more specific property if desired. For example above /forms/APP/assets/my-app.css
is repeated.[SINCE Orbeon Forms 2017.1]
In addition to
oxf.fr.css.custom.uri
, you can also use the following properties, which apply only to the Summary and Detail pages respectively:Disable the minimal and combined resources. When working on your CSS, you might want to temporarily set the following properties in your
properties-local.xml
, which will disable the combined and minimized resources, so the files and line numbers you see in your browser correspond to what you have on disk.```xml
<property
as="xs:boolean"
name="oxf.xforms.minimal-resources"
value="false"/>
<property
as="xs:boolean"
name="oxf.xforms.combine-resources"
value="false"/>
```
Note that with the [Form Runner Liferay Proxy Portlet](/form-runner/link-embed/liferay-proxy-portlet.md), you cannot disable combined resources as URL rewriting does not work in that case.
Know which class names to use in your CSS selectors. We strongly recommend you use the Chrome Dev Tools to check which classes are generated by Orbeon Forms. Once you have your CSS working with Chrome and/or Firefox, it is likely that the CSS will work with other modern browsers.
Orbeon Forms standardizes on the following prefixes for CSS classes:

You can either:
- 1.Store your CSS is a separate CSS file, which you either provide in addition or that overrides the default CSS provided by Orbeon Forms. For more on this, see the
oxf.fr.css.custom.uri
configuration property. This is the recommended technique if your CSS is intended to be shared by several forms. - 2.Put your CSS inline, in the form. Uf your CSS is quite short, and specific to a given form (not to be shared amongst forms), this is a possibility. For this, put the rules within your own
<style>
section of the form:<xh:title>My Form Title</xh:title><xh:style type="text/css">#fr-view .fr-grid .fr-grid-content .my-class input.xforms-input-input {width: 8em}</xh:style>
NOTE: Since 2018.1, it is no longer recommended to place any inline CSS, as some servers use the
Content-Security-Policy
header to disable inline scripts and CSS. Orbeon Forms 2018.1 doesn't include any inline scripts and CSS anymore by default.Bootstrap, XForms engine, Form Runner and Form Builder CSS rules are contained within an enclosing
.orbeon
CSS class. This ensures that the Orbeon CSS rules only apply within an element with that class. It also makes Orbeon CSS rules a bit stronger (more specific) than before. You might have to update your custom CSS to take this into account.When defining your own CSS, make sure to use a strong selector, so its precedence is higher than CSS provide by Orbeon Forms, e.g. something like:
.orbeon .fr-grid .my-class .xforms-input-input {
...rule...
}
Since Orbeon Forms 4.0, Form Runner uses Twitter Bootstrap for some aspects of its layout and styling.
NOTE: If you have custom CSS which works with Orbeon Forms 3.9, it is likely that you will have to update it to work with Orbeon Forms 4.0.
The default width with Bootstrap is 940px, but you can change this by overriding the Bootstrap/Orbeon CSS. As usual, to do so, we recommend you use a tool like the Chrome DevTools to find the exact rules you need to override in your environment. For instance, with an out-of-the-box Orbeon Forms deployed as a servlet, you can set the width to 720px with:
.orbeon .container, .orbeon .span12 { width: 720px }
