I wonder what could be the better way to simulate double buffering for some possibly complex SVG. I'm reloading often a modified SVG, and I'd like to get rid of the load delay. I was thinking of using two overlapped DIVs and toggle visibility after onLoad. There is some better alternative?
edit
Now I have implemented two SVG instances in DIVs overlapped, with style display toggling (block/none). It almost worked in FF (nice, smooth morphing, just initial display resulted in reduced area), but Chrome refuses to get me the ScreenCTM transform I need for syncing shapes position. I guess those problems (partial area render in FF, no render in Chrome) are related. Now I'm experimenting with visibility:hidden instead.
edit
toggling visibility give acceptable results. Thanks everybody for the help so far.

I've found a problem, that make me here again for an helping hand:
I'm using Boostrap for non SVG related UI, and the toolbar behaves really strange: when I switched visibility on the 2^ DIV (initially hidden), no event arrives to the toolbar. Switching again to the 1^, events are ok.
I found that using position:absolute or position:fixed is the same (for the events problem, of course), and top:0 it's the 'culprit'. Using any value > 0 let the event flow, but the DIV goes invisible. So the intial question make sense: any better method than switch visibility? or a hint on html structure? Currently my HTML looks like
<div class="row-fluid" style="height:800px;background-color:cyan">
<div id="flowchart" style="visibility:visible;width:100%;height:100%"></div>
<div id="flowchart_x" style="visibility:hidden;width:100%;height:100%;position:absolute;top:0"></div>
</div>

I'm trying to get create a custom ionic control that will have an autocomplete drop-down. Normally how I would go around this is by creating a nested element of position:relative; followed by an child element with position:absolute;
But for some reason when I tried it on my control in ionic the control get's clipped. Initially I thought to assign a simple z-index would ought to do the the trick, but to my surprise it did not have any effect. Upon some close reading it seems to have something to do with stacking contexts; to make it worse it seems that ionic also marks elements .item-md as position:relative
Any idea how i could make a simple example like this work?
Edit:
I tried to reproduce the case in a simpler setup, but generally, it seems my concept should work. When I put it inside of ionic it gets clipped again.
https://jsfiddle.net/4exLpcv5/
I had a similar situation. Try this for the affected element:
overflow: visible;
After a lot of fiddling around and inspecting the dom tree I was able to partially recreate the problem in jsfiddle. The overflow: visible as mentioned by #willactual is part of the awnser.
Ionic's .item have overflow set on hidden. Which in forces the browser clip out of bound rendering. When I reset the overflow to visible at least in my minimum recreation it behaved as normal. However, trying to bring my example into an actual ionic application, still made the element got clipped.
Now the second part of the solution I stumbled upon by accident is the contain: content. It seems over the years CSS has had some extra properties to act as performance hints. Be it, that ionic actually makes use of these hints and set's the contain property which in result clips the html element.
I'm trying to implement a linear-gradient on the html tag so that when the user overscrolls it will appear.
I can apply css background-color to the html element to allow the colors to appear like they extend above and below our page to make overscrolling less jarring or 'native.' This is sometimes referred to as 'rubber banding.'
A great example of what I mean can be found on Peter Ramsing's site. His example is below:
However, background-color seems to be the only property that works like this. Here is an example of the difference in behaviour between background-color and background-image (linear-gradient) - apologies for the gif quality:
You can find the markup to replicate the issue on codepen - this cannot be replicated within codepen itself unless on debug mode so I suggest forking this link to test.
It would be nice to have the option to have any background property extend and take rubber banding into account. I don't think there's a work around for this so I'm looking to see if anyone would know as to why Chrome team have not included this as a feature?
If no one knows as to why I'm going to submit a bug/feature request for this.
When setting a background to the html, it will be applied on all four borders. If you just want to have a background-color on e.g. the top site, add a div element above your page:
<div style="height:1000px;background:#00BD9C;margin-top:-1000px;position:fixed;width:100%;"></div>
By that, the overflow color will just be applied on the top side. Depending on the background configuration of your inserted div, you can make there also gradients or insert an image that will be shown on overscroll.
Background:
I'm trying to create a rotating image banner with several links, each link being different. The FIGURE are set inside a DIV which is nested inside another DIV for centering and positioning purposes.
Current JSFiddle:
Available here without WebKits.
Problem:
Although I tried with several combinations, inside the markup and CSS, never does it trigger the anchor in any of the images (I have not set any effect on hovering yet, not to confuse the code). I deleted the anchors so you can see the base code before the tests I did. It functions now as perfect Pic Slideshow, yes, but that is not the intent.
Need:
To know what to do with an A tag for it to work on each of the images separately, in order to transform the PIC SLIDESHOW into an alternative to a Slider.
Code type restrictions:
I do not wish to use a JQuery in the solution, only CSS, HTML and the smallest JavaScript possible if everything else fails
Many Thanks
We wanted some numbered lists and found this cool counter thing you can use in you css to have the browser calculate numbers for you:
ol.instructions {counter-reset:instructions-section;}
ol.instructions > li:before {
content:counter(instructions-section);
counter-increment:instructions-section;
}
The html we're making contains pages of instruction sets, each set numbered from 1,2,3 and so on. Only one set is visible at a time, when you click a header you show that set and hide the others.
It worked like a treat and we were sitting there with smiling faces until someone thought of testing it in Internet Explorer 8, where we ran into some epic Microsoft-style weirdness. When a set was brought up by clicking, all the numbers were zero (0).
I googled around and found this page - it describes the problem fairly well (it's a combination of using :hover and css counter logic used in hidden content), but gives a solution that is less than satisfactory - I would love to be able to keep using the css counters and just implement some ie8-specific hack that somehow makes the page update the numbers. I'm having a hard time finding other stuff on the internet about this problem.
My particular page will describe zeroes until I move the mouse pointer into the div that contains the numbered list, at which point the numbers will magically fix themselves. Is there something I could to "nudge" the page into believing that a mouse is hovering over the element? Or is there a more proper solution?
Ive had the same issue. I was able to fix it by using JavaScript to apply inline CSS of padding-left 0 (there was already no left padding) once the element was visible. This seems to make IE 'redraw' the element.
If, as is suggested, the "hidden" is causing a problem then you could try "hiding" the content by instead moving it off screen with this piece of CSS:
.hide {
position:absolute;
left: -1000px;
}
I've used the code example from the linked to document to show a possible solution here: http://codepen.io/akademy/pen/LDhGl
i'm solving a problem to make select inputs look the same in all browsers (Chrome and Safari on Mac renders them differently) how to do that ?
The ONLY way to make them look the same right now would be to hide the original inputs, and replace them with appropriately styled html equivalents (of god forbig Flash objects), which would act as proxies, passing the functionality over to the hidden inputs.
That may be automated with JavaScript. But that would be WRONG. You are not supposed to force a different look on to OS styled elements of the webpage. It conflicts with a lot of usability and accessibility practices.
So, the only way is to make your design flexible enough to support differently looking control elements on a web page, and also use different stylesets for different browsers, to ease the adjustment of the styles (at the moment there are no inputs that would look and act the same on all browsers with the same style rules applied).
Unfortunately, life just kinda sucks on this one. Just wait till you need to style a file input...now that's some fun!
if you dont mind using js you can simply design your own look (a jpg img it can even be the same img as the original select element or if you wish you can model parts of it in css)
Then place a div on top of that image that div will contain the text which select element would usually contain
<div id="selectTxt" >
then set another div on top of that with the select element inside it.
<div id="transparentSelect" class="transparent">
<select id="selectCar" name="selectCar">
<option>Volvo</option>
<option>Saab</option>
<option>Mercedes</option>
<option>Audi</option>
</select>
</div>
Now the trick is to set the select element opacity to zero
you can do this by adding by adding a class transparent
and then applying the class to the div
.transparent
{
filter:alpha(opacity=0);
-moz-opacity: 0;
opacity: 0;
}
now the element is hidden but when you click on it the list will still show up.
So the list will always look like the default list in the browser
now use js to extract the select value every time you click on the select
and set the inner html of selectTxt div to its value.
This way you get the text of the select on top of an image you want
you can make the image animated with the hover effect in css or with js
I also make a select that looks the same in all browsers but it doesnt work when you click directly on the arrow...
so its an inferior version but if you wish to look at it here it is
http://jsfiddle.net/fiddlerOnDaRoof/LM73V/
it also lacks the arrow image but you can print screen that from your browser
good luck
You should apply a CSS to reset the styles (not just for the inputs, this is a highly recommended practice for all element so that your page looks almost the same in all browsers) there are many, just google a little, for example this one, and then apply your desired styles (border color and width, background, etc...) take a look at this tutorial on how to style form elements
