Element HTML and CSS guidelines

In the form designer of the Content Studio app you have basic capabilities to influence the styling. For example you can change the sequence of fields and the placement of field labels. Since release , you have the option to embed the form into the new landing page and there you have additional options to change the style of your form. For example you can change the color of the button and the button text. If you need more advanced capabilities for styling your form, we support the definition of a custom CSS file in the form designer.

In this article, I want to give you an overview of the preconditions and process to improve the style of your forms. I also intend to build on this article and publish a series of posts on specific improvements you can do with CSS.

Before you read any further, I want to point out that this will become very technical and that you should have the following:. Also please note that all CSS code I present here come without warranty — you need to try out for yourself and test everything thoroughly — especially for multiple screen sizes, devices or browsers! A good way to check the global compatibility of any CSS property you might want to use is caniuse. When this policy is fully effective any external CSS file will be blocked.

Therefore, you need to add the domain of the web server where you store your CSS files to the CSP whitelist as follows:. In the context of the form designer this really means every element of that web page! At worst this could make the UI unusable! A slightly related problem is that you might need to do some styling, which influences the very layout of the form elements.

For example placing 2 input fields side by side on the same line. While this might be a valid use case for the runtime form such layout changes also have the potential to break the UI of the form builder. The result would be issues arising when you add new fields or move fields around.

As a workaround I recommend to restrict the effectiveness of the related CSS styles to the display mode or runtime only — or in other words to block those styles for the edit mode. Every browser has tools to investigate the details of any web page. To activate the tools you need to check your specific browser. The most intuitive way for me is the inspect option, which should be available in every browser when you hover over an element that interests you and then press the right mouse key.

So, if you want to create a style for a specific field on your form then you just need to hover over that field and invoke the inspect option see popup in the screenshot above.

Note: You might have a form embedded in a landing page. If you invoke the inspector in this case, you will not get to that field because the form is embedded in an iFrame and the inspector will land on that iFrame level. Therefore, I recommend you do this in the form designer and not in the landing page designer. If you absolutely want to do this in the landing page designer, then the quickest way I found is to invoke the inspector and then do a search for the field label you are looking for.

Once the inspector is active you will see a split screen with the HTML code in one part bottom part of screenshot and the page on the other part top part of screenshot. You can now hover over the different HTML code lines and see the corresponding areas highlighted on the page view. The next useful feature is the style info panel see bottom right in the screenshot. Here you can see exactly which styles have been loaded and what the sequence is in which they are evaluated priority goes from top to bottom.

So, if you created a style and you wonder why a particular style attribute is not working then you need to look here and find your stylesheet reference. Most likely that style attribute has been invalidated strike through because the same style attribute has been used in another style, which lies above your style.

In that case, you need to find ways to make your style more important. By doing so, you will see any effect a change has immediately on the screen. After you have created your CSS stylesheet file and uploaded it to your web server you need to assign it to your form:.

Usually there will be some changes in the CSS stylesheet after this assignment. In that case, you might need to clear the cache of your browser before reloading the form. You create a custom class by defining a style in your CSS stylesheet, which uses that class as a selector. Please note that you can assign multiple classes here, for example one for the text color and one for the background color. Also please note that you need to enter the class name without the dot that you see in the example code of the stylesheet above:.

In the browser development tool, you will also see the result of this. But since attributes often get inherited by their children this works in that case. In many cases you might want to style only children of the DIV element with that custom class. Also, I will only focus on the structure and attributes like IDs and classes. In the code, you will find other attributes that are not relevant for styling. I also will not explain all the classes here — I encourage you to look for yourself in the code using the browser tool explained above and experiment.

In the parameters of each field you can specify the indentation or switch the indentation off. Label is positioned left from input field exception: For checkboxes the label is right from the checkbox No Indentation.

The structure may vary depending on the type of the attribute:. After reading this post you should be able to do some basic styling of your forms with CSS stylesheet. Other posts of my CSS series:.

Do you know if it's somehow possible to deactivate the submit button after a successful form submission? During the form submission the button is deactivated, but after the success message is returned the button becomes active again. We'd like to be able to prevent repeated submissions. Of course using the "open follow-up page" option is also available but if possible we'd simply like to display the success message.

Excellent work Arne Manthey! Hi Arne Manthey. We noticed that Codelist fields on a form will always sort the dropdown values alphabetically. So in different languages, the order of the values is different. We have for example a field with the value "Other" and this appears at a random place within the dropdown list, instead of at the end and in French, it translates to Autre, and makes it appear at the top of the list even.

There's no option to make it sort on the Code, it can only sort on the Value December 10, 11 minute read. Some good starting points are: w3. In the Managed by Customer section, click New and enter the domain of your web server.

Caution — Do not Break the UI! This would be very unspecific. By doing so you will never influence any UI element of the form designer. However, this is only valid, if the styles of those classes will not change the layout of fields see next paragraph A slightly related problem is that you might need to do some styling, which influences the very layout of the form elements. Enable your CSS Stylesheet After you have created your CSS stylesheet file and uploaded it to your web server you need to assign it to your form: Usually there will be some changes in the CSS stylesheet after this assignment.

CSS Classes and Document Structure There are two things you might want to do: Create new custom classes, which then can be used to apply a specific style to specific form fields Influence the general styling of the entire form or every occurrence of a specific form type explained at a later time Custom Classes You create a custom class by defining a style in your CSS stylesheet, which uses that class as a selector.

Also please note that you need to enter the class name without the dot that you see in the example code of the stylesheet above: In the browser development tool, you will also see the result of this. Also remember my earlier comment to avoid breaking the UI? This is the same class that you should generally use for the start of every selector. The next element is a DIV that you can probably ignore for your styling — it just adds some additional padding around the form.

Finally, you will find the elements that you dragged onto your form canvas input, checkboxes, buttons,…. Depending on the type of the element there will be additional classes, which let you select only certain types of fields for your style. The structure may vary depending on the type of the attribute: Normal text field e. First Name Dropdown list e. This includes a download link. Alert Moderator.

Mailing lists, contact forms, and blog post comments are common examples for small websites, but in organizations that rely on their website for revenue, forms are sacred and revered. There are two aspects of a functional HTML form: the frontend user interface and the backend server. The former is the appearance of the form as defined by HTML and CSS , while the latter is the code that processes it storing data in a database, sending an email, etc. As you can see, this is a speaker submission form for a fake conference. It hosts a pretty good selection of HTML forms elements: various types of text fields, a group of radio buttons, a dropdown menu, a checkbox, and a submit button. Hey look! It has some semantic HTML!

People who have certain types of color blindness will be unable to determine the input's state unless it is accompanied by an additional indicator that does not rely on color to convey meaning.

CSS is designed to enable the separation of presentation and content, including layout , colors , and fonts. Separation of formatting and content also makes it feasible to present the same markup page in different styles for different rendering methods, such as on-screen, in print, by voice via speech-based browser or screen reader , and on Braille-based tactile devices. CSS also has rules for alternate formatting if the content is accessed on a mobile device. The name cascading comes from the specified priority scheme to determine which style rule applies if more than one rule matches a particular element. This cascading priority scheme is predictable.

Since we first released our Modern form and Form designer just about a year ago, we've received a lot of praise as well as constructive criticism and improvement suggestions. Many of those suggestions have to do with the look and feel of the forms, customer are always trying to push the envelope and design even more visually-striking forms and we completely support and encourage their efforts!

CSS classes are a convenient tool for changing styles and playing animations programmatically. As an alternative to hard-coding classes with JavaScript strings, Stimulus lets you refer to CSS classes by logical name using a combination of data attributes and controller properties. Define CSS classes by logical name in your controller using the static classes array:. Construct a CSS class attribute by joining together the controller identifier and logical name in the format data-[identifier]-[logical-name]-class. Note: CSS class attributes must be specified on the same element as the data-controller attribute.
