Make text inside the textbox uppercase

We use a form for personalized embroidery orders.

Is it possible to force capital letters in a text box?

If you are planning to make the text uppercase in the all text boxes in your form then you can use this custom CSS code.

.form-textbox, .form-textarea {
    text-transform: uppercase !important;
}

But if you're planning to apply it on 1 textbox only, then here's a guide.

1. Select the field and then click the gear or options icon. Choose "Show Properties".

2. Get or copy the field ID (#input_1).

3. Inject this custom CSS code targeting the field ID.

#input_1 {
text-transform: uppercase !important;
}

Here's a guide on how to insert custom CSS on your form.

Hope that helps. Thank you.
