Visibility Bug

Nodral · October 11, 2011

Hi All

Not sure if this will sit with CSS or Javascript as it's a bit of both. This code works fine in FF but in IE7 (which most of my audience use) it has issues.

The process should be that the user clicks the first button and it hides the first and shows the second. The user clicks the second button and it hides the second and shows an input form.

However I have 3 issues which I cannot understand.

[*]The main 500 line input form shows from the start in IE7 even thought the visibility is set to hidden until the button is pressed.

[*]I cannot set the cell width in the input form regardless of what px i put in, it stays the same (this occurs in FF too)

[*]In IE, when the form is finally set to visible, I get borders around the text input fields, again these are set to hidden

See code below

After a couple of years of using visibility and a bunch of headaches later, I decided never again to use visibility and just use display.

IE: display = 'block'; or display = 'none';
