123FormBuilder forms are responsive to all mobile devices and tablets. Our forms work great on all devices and are offering a user-friendly experience on any device.
Our forms are by default mobile responsive, however, you can tweak your existing web forms with CSS. In this article we will show you a step-by-step guide on how to accomplish that.
When you insert an image in the Form Header or HTML blocks you will need to specify the best settings to ensure that it will be responsive. In the editing mode of your HTML field click the plus sign and select Image.
After you upload the image type at width 100% and auto at height. Disable the Constrain proportions option to maintain the original width and height dimensions.
When you add an iframe to display a video you can use a custom CSS code to make it work perfectly for mobile devices. The CSS will be placed in the Edit – Themes – Add Custom CSS section. This method applies to all iframes. Simply, copy paste the code from below:
iframe{
height: auto;
width: 100%;
}
Font size may seem like a small thing, but it is an important element, especially for mobile readers. You can use the following CSS and adjust the number of pixels(12).
@media only screen and (max-width: 550px) {
#form *{
}
Enlarge the submit button to have a better visibility. The CSS code from below will make the submit button wider.
@media only screen and (max-width: 550px){
#form button[data-role] {
padding: 0px 33%;
}
}
Decrease the percentage number if you want the submit button to be more narrow or increase the number (33%) to make it wider.
To make the font size of text button smaller simply adjust the number of pixels.
@media only screen and (max-width: 550px){
#form button[data-role] {
font-size:12px;
}
}
That’s it! Now your forms are fully responsive and form users will have the best user experience.
