I have three buttons on my web page. On the click of one button, a process starts, and after a certain period of time, an alert will show "process complete".
How do I lock the screen from any further user input until that time?
The easiest way would be putting a div element on top of everything else, with a very high z-index.
<div id="blur"></div>
CSS:
#blur { position: fixed; left: 0px; right: 0px; bottom: 0px; top: 0px;
z-index: 999; display: none }
The display: none is so it doesn't show up right away. Use JavaScript or jQuery to change the display property to "block" (or use jQuery's .show()).
For further effect, you could give it a slightly transparent milky background:
background-color: rgba(255,255,255,0.5);

I have an annoying issue with the html layout of a form. I cannot really change the general setup, since it is part of a huge framework. But I have to "move" a button to a more suitable location. I am close, but not happy with the solution so far. Maybe you can give me some idea in this. Here is a dramatically simplified version to demonstrate my approach:
I have two container divs, top and bottom.
The top container shows a button on the left side. That button is fixed, but can have a different width due to the translation of its label.
The bottom container holds lots of stuff. Amongst that a second button at its top which works fine, but looks wrong. I want to optically move it into the top container, since there is a logical connection to the button in there. Sure, really placing it in there would be the correct solution, but I currently cannot do that. Instead I use a fixed position which works fine, except for the horizontal placement. I have to decide how far pushed from the left to place the button, so that it certainly does not overlap the first button in the container. I obviously have to consider all translations, the result works, but depending on the first buttons label I have an annoying horizontal gap between the two buttons.
I tried to use a pseudo element (::before) on the second button to help with the layout. Since when rendering the view I obviously have the translated label of the first button I can copy that into some property of the second button and use that property in my css to fill a before pseudo element of the second button which has exactly the same length as the first button. That is what is shown in the code example posted below.
What I completely fail to do is to place that pseudo element such that is it left in the top container (so exactly below the first button). The idea is to indirectly place the second button that way. Looks like this is not possible, obviously. But since I am a bloody beginner in markup and styling I thought it might be worth asking here...
Below is some drastically stripped down code to demonstrate my approach.
I create a jsfiddle for you to play around with. Here is the code:
HTML:
<div id="top-container">
<button>multilingual button text</button>
</div>
<div id="bottom-container">
<h2>
Some title opening the bottom container
<span class="into-top-container">
<button id="place-me" reference-text="multilingual button text">button to be placed</button>
</span>
</h2>
<p>Some content</p>
<p>Some content</p>
<p>Some content</p>
</div>
CSS:
body {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
}
div {
margin: 0;
padding: 5px;
}
button {
margin: 0;
padding: 5px;
white-space: nowrap;
}
div#top-container {
width: 100%;
border: 1px solid green;
}
div#bottom-container {
width: 100%;
border: 1px solid blue;
}
#place-me {
position: fixed;
top: 0;
left: 400px;
margin: 5px;
background: yellow;
}
#place-me::before {
z-index: 0;
/*visibility: hidden;*/
position: absolute;
content: attr(reference-text);
margin: 0 5px;
padding: 0;
background: gold;
right: 100%;
}
Notes:
that in the above code the second button is placed with left: 400px;. That is more or less what I want to change. But obviously left: 0 is not correct...
the visibility css rule for the pseudo element is currently commented out for demonstration purpose
keep in mind that the second button is *not* contained inside the top container, but actually logically below the title of the bottom container. The goal is to move it optically up into the top container which already is where close to what I want. Except for the horizontal alignment...
Upon request here is a screenshot:
It is taken from the fiddle I posted above. I added the red ellipse which shows what element pair I want to move and the left pointing arrow indicating where I want to move that too. I want to move it exactly that far, that the two tests "multilingual button text" are exactly placed on top of each other, but without specifying an explicit left placement obviously. That is why the pseudo element exists: as a dummy placeholder. I would then hide that pseudo element and have the second button placed exactly right of the first button, regardless of how long the translated text in there is.
So the final result should like like that:
OK, I invested some more time, since this issue popped up again after a regression in our code and I found, as often after allowing some time to pass, a logical and relatively clean solution:
I use the same stripped down code to for demonstration purposes.
The jsfiddle is based on the one provided in the question itself.
HTML: no real change, except for the reference-text having moved from button to container, for the why see below:
CSS:
* {
font-size: 12px;
font-weight: normal;
font-family: Arial;
}
body {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
font-size: 12px;
font-weight: normal;
}
span,
div {
margin: 0;
padding: 5px;
}
button {
margin: 0;
padding: 5px;
white-space: nowrap;
}
div#top-container {
width: 100%;
border: 1px solid green;
}
div#bottom-container {
width: 100%;
border: 1px solid blue;
}
span.into-top-container {
position: fixed;
top: 0;
left: 0;
pointer-events: none;
border: 1px solid transparent;
}
span.into-top-container::before {
visibility: hidden;
content: attr(reference-text);
position: relative;
margin-right: 5px;
padding: 5px;
border: 2px solid;
background: gold;
}
#place-me {
background: yellow;
pointer-events: all;
}
The basic change in strategy: it is the container holding the button to be placed that has to be positioned in a fixed manner, not that button itself (so the <span class="into-top-container">)! That allows to use the pseudo before element, now also anchored to that container, not the button, to take the space as required without actually getting part of the button itself.
Since that container is now place over the original multilingual button that one is not clickable any more. That issue is fixed by a css pointer-events set to none for the container and set to all for the placed button again. That makes the container itself simply ignore all events (clicks) and have them passed to the original button beneath.
I had to make sure that the font used inside the pseudo element is style exactly like the original multilingual button. That actually makes sense, since the font styling defines the actual width used by that button, so the actual width used by the pseudo element should be defined in exactly the same manner. In the example above I forced that by simply setting all elements font style rules to some fixed values (the initial * {...} in the CSS code). That can obviously also be done right inside the css rules for the pseudo element itself. I chose the more simple and brute variant here to keep the code clean.
How to open bootstrap-dropdown when i click on cell within ng-grid ?
I can open it only partially.
Here's plunker
I think you need to add this to your CSS:
.ngCell {
overflow: visible;
}
which allows the ngCell to display the drop down like you want. The issue that I'm having is getting the drop down on a lower cell to appear over the ngGrid footer rather than increasing the size of the scroll bar.
This CSS worked for me so something in this direction will hopefully work for you
.dropdown-menu {
position: fixed;
display: block;
margin: 22px;
top: auto;
left: 0px;
padding: 0px;
I just discovered this strange problem on an <a> element. I wanted to make a css only button with a "pushed down" animation.
More or less something like this:
.button:active {
position: relative;
top: 10px;
}
The problem is that link doesn't seem to work if you do the mousedown below the text and release when the text has moven below the pointer (the animation runs correctly but onclick or href don't work). You can see the "bug" or whatever it is in this fiddle:
http://jsfiddle.net/H9RgD/
I already tried different things, like using padding to create the animation but it still doesn't work. I can confirm it doesn't in Chrome 22 (latest version as of today). Why does this happen? How can I get around this problem to animate a css only button?
Cannot answer "why" (I think it may be a bug). It seems like I recall encountering a similar issue before with Chrome, and came up with a similar workaround as I offer here. Somehow, adding the "overlay" of the pseudo-element causes the whole to become "clickable." In your case, I noticed that if I clicked toward the top of the div, it also did not register, but when I added the top adjustment to the :before in the :active state, that seemed to be resolved also.
This fiddle seems to have a working solution. HTML is the same as your fiddle (except I added the content to the alert):
HTML
<div class="tabs-container">
<div onclick="alert('here')">Click below the text</div>
</div>
CSS
.tabs-container div{
display: inline-block;
background: whitesmoke;
padding-bottom: 5px;
font-size: 25px;
border-bottom: 5px solid grey;
position: relative;
}
.tabs-container div:active{
top: 10px;
border-bottom: 0;
}
.tabs-container div:before {
position: absolute;
content: '';
top: 0;
right: 0;
bottom: 0;
left: 0;
}
.tabs-container div:active:before {
top: -10px;
}
I've got a problem with the AutoCompleteExtender inside the AJAX Control Toolkit which I just can't seem to get to the bottom of. The control sits inside an asp:Panel linked to a ModalPopupExtender from the toolkit. Everything works beautifully in the latest generations of IE9, FF and Opera but glitches in Safari and Chrome (assuming it's WebKit related).
The glitch is that the drop down from the autocomplete is falling behind the modal popup rather than in front of it (names blurred for privacy reasons):
Looking at things in Firebug, here's the drop down rendered in an unordered list:
<ul id="EmployeeAutoCompleteExtender_completionListElem" class="autoCompleteList" style="width: 281px; visibility: visible; position: absolute; left: 0px; top: 22px; z-index: 1000; ">
The autoCompleteList class looks like this:
.autoCompleteList
{
list-style: none outside none;
border: 1px solid buttonshadow;
cursor: default;
padding: 0px;
margin: 0px;
}
And the resulting div for the modal popup looks like this:
<div id="MainContent_AddPeoplePanel" class="modalPopup" style="z-index: 100001; position: absolute; left: 719px; top: 352.5px; opacity: 1; ">
With the following modalPopup CSS class:
.modalPopup
{
background-color: White;
padding: 10px;
width: 462px;
}
My assumption is that the lower z-index on the list is causing it to fall behind the div but then again, it plays nice in the non-WebKit browsers. The z-indexes are also inline styles so they're obviously coming straight from the controls. Am I missing something here? Any suggestions? (other than ditching WebForms and AJAX and employing jQuery)
Seeing as you suspect it's the z-index causing the problem, what happens if you try and override the inline styles that are spat out by the Ajax Control Toolkit using !important?
.autoCompleteList {
list-style: none outside none;
border: 1px solid buttonshadow;
cursor: default;
padding: 0px;
margin: 0px;
z-index:2000 !important;
}
.modalPopup {
background-color: White;
padding: 10px;
width: 462px;
z-index:1000 !important;
}
I know it's a bit of a hack but if you haven't tried it yet it might be worth a shot?
Ian, I was having a similar problem with a modal popup and several callout extenders. The callout was always under the popup. I lowered the z-index of the modal with the !important and poof. Started working. Thanks much for the suggestion.
I have came across same problem.
My code was running pretty fine in mozilla. but it was not working on Safari and Chrome.
Now I set "z-index:12000 !important;" to autocomplete class, because modal popup has 10051 z-index value.
I have some problems with CSS and z-index. Let me show you an example
Suppose that on a first moment it only appears the tag pointers. Then, when I click one of this pointers appears a tag globe. I want that the tag pointers appears always under the tag globes, and I want too that every time I open a tag globe it appears over all other tag globes opened.
My div structure is:
<div id="t01" class="tag">
<div class="small">
<div class="globe">
<div class="in-globe">
<!--tag globe content-->
</div>
</div>
<div class="globe-arrow"></div>
</div>
</div>
And the related CSS code is this:
.tag {
z-index: 3;
position: absolute;
left: 0; /*JavaScript modified*/
top: 0; /*JavaScript modified*/
width: 19px;
height: 26px;
padding: 0 11px 10px 15px;
background: url('../../images/zoom/tag.png') no-repeat center;
}
.small {
cursor: pointer;
width: 19px;
height: 26px;
}
.globe-arrow {
position: absolute;
left: 23px;
bottom: 30px;
width: 8px;
height: 6px;
background: url(../../images/zoom/tag_arrow_UR.gif) no-repeat;
z-index: 5;
}
.globe {
position: absolute;
left: 23px;
bottom: 30px;
z-index: 4;
}
.in-globe {
font-size: 11px;
margin: 0 0 3px 3px;
padding: 3px;
background: #FFF;
border: 1px solid #000;
}
The 'tag' is all the conglomerate, and its background is the tag pointer image. However, this image has some shadows and I only want that a certain zone can be clicked. Then, the 'small' div has this function. The 'globe' and 'in-globe' divs are where the content of the globe is written (it could be an only div, there are two for historical reasons), and the 'globe-arrow' div is basically a little image to show this small arrow over the globe.
With this structure it doesn't work. In a same conglomerate, a globe is always over a tag, but an entire conglomerate defined before in the html code appears entirely under a newer one. In the same way, although a globe is inserted by JavaScript always after an older one (logically) the tag conglomerate is inserted when the page is loaded and then the overlapping works like I said.
Can you propose an smart way to reach my objective? Think that I'm interested on positioning the globe respective to the tag, because when I drag a pointer with a globe opened I want that the globe moves with it by CSS, not by JavaScript.
give .globe-arrow a z-index of 3
I solved the problem. There's no magic way to do it. I had to change the way I structure tags. It seems that z-index inherits from the container div, then like the parent has less z-index, a son of another parent with the same z-index appears under the first although this son has a bigger z-index. It's very confusing, yes.
In few words, I define a tag-container (to positionate the tag), into it I define a pointer and a tag globe. The first with less z-index than the second. Now, as all the divs with z-index has the same level all tag globes appear over all tag pointers.
I want that every time I open a new tag globe it appears over the opened globes. Against my desires, I had to use JavaScript for this because with a same z-index the browser show over the last defined div. This is ugly. I build a stack of z-index's that increases with more globes and decreases when I close them. Then I simply edit the css dinamicaly to put this new z-index to the new globe.
Thank you for your attention and help :) I hope this could be useful for somebody.
