hidden

I have a div that I use to display alerts when needed. If I want to close it after a while can I use display:none or should I use display:none as well as visibility:hidden? So one or both. Thank you. Depends. If you need the space to be left blank, that is, the space won't be taken up by other elements below or around it, you'll need visibility: hidden . Otherwise, use display: none , which will allow other elements to move into the element's place. There's no reason to use both. If your hidden content needs to be accessible—to those with screen readers, for example—then you should not use

I would like to have some Magento product attributes that are not editable from the admin interface and some that are not visible at all in that interface (as a method of storing some persistent information about a product that should not be viewed by human users.. it's the only way of doing this that i can think of, any other suggestions are welcome). So my question is: Do all Magento attributes have to be visible and editable from the admin interface? If not, how can they be made read-only or hidden? I noticed that in the admin interface there are some read-only fields, so it must be

I have a question about UIView , what's the difference between views hidden, alpha and opaque? The effect of setting view: hidden = yes and view.alpha = 0.0f is the same. The differences are subtle. According to the UIView class reference : opaque tells the system that the view has no transparency and is thus faster to render because calculations for blending can be skipped hidden is boolean property that changes only the visibility of the current view and hides it from ui events. alpha is an animatable property Setting alpha = 0.0f or hidden = YES has the same visual effect. However using

I have a form(like the one below for example) where I type data, but I also want to send data which are not directly entered by the user, for example a generic Id(for a user in this case) <form name="input" action="" method="post"> Username: <input type="text" name="user"> <input type="submit" value="Submit"> </form> Don't know if I have been clear enough, I hope so. try a hidden input: <input type="hidden" value="foo" name="user_id" /> The user can't see it, but remember that such inputs can be spoofed and need to be validated on the server just like any other input. 来源： https://stackoverflow

How can I add files starting with dot (hidden files) in git repo? Git seems to always ignore those. When I type git add . , dotfiles in GIT_DIR are added, but not from subdirectories. On the other hand, git add subdir/.dotfile won't work. I tried git add -f and putting !.* in GIT_DIR/.git/info/exclude . No luck. git add . and git add dir/.dot work fine for me with the unadorned 1.6.6.1 and 1.7.0 versions of Git that I have handy right now. % git --version git version 1.6.6.1 % git ls-files -o .baz/baz .foo bar/.bar quuux/quuux quux % git add . % git ls-files -o % git ls-files .baz/baz .foo bar

When using CSS overflow: hidden , I've often found that the last line of text gets partially cut-off. Is there a way to prevent this so that any partial lines do not show-up. Almost like a vertical word-wrap. You can use wrapper div and multi-column css: .wrapper { -webkit-column-width: 150px; //You can't use 100% column-width: 150px; height: 100%; } Solution example: http://jsfiddle.net/4Fpq2/9/ Update 2017-09-21 In Firefox this solution still works but broken in Chrome. Recently Chrome started break column by small parts, also stop break content if you set height. In this http://jsfiddle.net

I want to generate html layout with areas (divs, spans) that can be shown/hidden conditionally. These areas are hidden by default. If I call .hide() method with jquery on document.ready these areas may blink (browsers render partially loaded documents). So I apply "display: none" style in html layout. I wonder what is the best practice to avoid blinking, because applying "display:none" breaks incapsulation rule - I know what jquery does with hide/show and use it. If jquery's hiding/showing implementation will change one day, I'll get the whole site unworkable. Thank you in advance There's
