501959 - Setting a style on <input> causes <input type="hidden"> to display

Status: RESOLVED DUPLICATE of bug 436046

(Core :: Layout: Form Controls, defect)

Description

[Dave Simon]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_5_7; en-us) AppleWebKit/530.17 (KHTML, like Gecko) Version/4.0 Safari/530.17

If a general input style is created, input type="hidden" follow the styling. This is not expected behavior. I shouldn't have to add a class="hide" and a style .hide { display:none; } to make hidden fields hide. That's why they are called hidden.

This behavior doesn't happen in WebKit or even IE. It's been in Firefox for ages. Sure, the fix is a class added to a field, but sometimes that's not available (when a script is used to create the actual form, such as a Google Search box.)

Yes, this can be solved with Javascript. It shouldn't have to be. It's a bug. Not a feature. Bug. Fix it. :)

Reproducible: Always

Steps to Reproduce:
1. Create an input - <input type="hidden" value="bet this shows up" />
2. Create a general input style - input { display:block; height: 25px; background-color: #fff; border: 1px solid #000; }
3. Enjoy all the hidden fields being shown all over your form.
Actual Results:  
Inputs of type="hidden" are displayed if there is a general input style in the stylesheet.

Expected Results:  
Inputs of type ="hidden" shouldn't show.

This looks like bug 222482.

Actually, we just went ahead and made it impossible to show the hidden input, because people apparently don't stop and think about what their CSS rules mean...

In Firefox 3.5.3 setting the display property of the INPUT element to a value like 'block' or 'inline-block' will cause hidden inputs to be displayed

Right; bug 436046 is fixed in the Firefox 3.6 alpha and later.
