I imagine that the answer to this question is no, but just in case I'm going to ask it anyway.
I want to use know if it is possible to use html5 drag and drop functionality without adding markup to the html (i.e., without adding draggable="true".
The reason I'm asking is because I want to use this within TinyMCE but I do NOT want to publish to the front end dragabble="true". I only want the drag and drop to function in the backend.
Any ideas?
P.S. I imagine I could see if there is a filter within TinyMCE for when the content actually gets published to the front end, but I would first prefer to see if it is possible to do this without a filter.
These things are draggable by default (ie. without any kind of attribute):
Links
Images
Selections
If you can make everything you want to be draggable be one of those things then you're OK, you just have to handle the events in the normal way. The easiest ways I can think of are:
Absolutely positioned images as 'drag proxies' (if they're absolutely positioned then they'll be out of the document flow)
Automatically select text on mouseover
However, I think it would be far more simple to add and remove the draggable attributes dynamically, eg. with jQuery (perhaps in the save event of TinyMCE):
$('#editor *').removeAttr('draggable');

Long ago at a conference talk on React I saw the presenter add something to his code that allowed you to click-drag a divider on the screen by getting to within a certain number of pixels of it, rather than have click exactly on it.
It's a handy concept for improving usability, though I don't know what it is called. Adding 'slop' perhaps? Anyway I completely forget how he did it, presumably using some padding approach. Does anyone know what this practice is called and how to implement it? I assume it was something he achieved it with CSS but am not sure.
You can use vanilla js to do that. Using element.getBoundingClientRect() to retrieve the element's offset relative to body and comparing with the actual mouseX and mouseY(in the click moment of course) you now know the distance between the element and the click, now add some logic like: Case distance < acceptable offset then do some side effect.
I wish to animate a page always from the right when switching between two pages. Why? Because the 'next' page is always dynamically loaded. Is there a neat way to do this? I am self answering with a hack, however I am looking for a way that isn't messing witht the DOM.
It is possible to achieve this effect by switching the DOM order of the elements instead of switching the selected property of the <core-animated-pages>. A way to do this can be found in this answer. The disadvantage is that it makes is very hard to switch between transition types (if so you were to wish) and makes for some ugly code either way.
Is there an easy library out there to do something along these lines:
I have a page with a lot of elements. At any given time I want to be able to put a modal on top of the entire page and just highlight one of the pre existing elements on the page to draw attention to it.
Most of the libraries I've seen revolve around dialogs that pop up and then hide the rest of the page. Are there any easy alternatives?
Thanks!
You can use a BlockUI script, then raise the single element's z-index to be above the block.
However, you'll need to make sure it's in the same stacking container; you may need to move it to the <body> and position it absolutely.
I'm using the excellent BeautyTips plugin as a means of indicating validation failures to end users and I'm running into positioning problems whenever page content is dynamically added, removed, or animated.
Here's a concrete example. I have a DIV at the top of each page that’s used for confirmation/error messages. It's displayed in $(document.ready) using slideToggle(). This naturally "pushes" all subsequent html content down, throwing off the positioning/alignment of the beautytips. If I call the plug-in's built-in refresh method after slideToggle() has fired, said positioning problems are corrected. You can see the before/after screen-shots here and here.
One possible workaround would be to programmatically detect DOM changes, specifically changes to css, so that I could then loop over each beautytip and manually reload it. However, it appears that there are no native jQuery events which expose such functionality. I've seen the impressive jQuery plug-in by Rick Strahl that monitors CSS changes, but it seems based on the assumption that one knows ahead of time the specific HTML element(s) they wish to monitor. I want to monitor the entire document, since I can't be expected to know what html elements might exist on a given page that a) are going to be animated and b) would be at such a position in the document that they would "push" down the my beautytips. And I certainly don't want to have to incur the massive performance penalty of polling every block level element in the document.
I should mention that the plug-in works perfectly if I use it in its default "hover" mode in which beautytips are displayed only in response to user mouse input. Unfortunately, there is a design constraint imposed on the application that states all validation errors must be displayed after form submission without additional user interaction.
I'm sure there's a really simple/elegant fix that is completely eluding me. I could avoid all of this hassle, of course, by simply not using animation to display page content, but that seems like a high price to pay.
Is it possible to use CSS to work like frames?
What I mean is, when we use frames (left, right for example), clicking on left will refresh only the right section using the 'target' attribute.
Is it possible to create this effect with CSS?
Thanks.
Using frames is usually a bad idea
To answer your question, no, CSS cannot be used to work like frames. CSS is used to changing the style of HTML and as such, cannot actually change the content of a page. It can be used to hide content, but I don't think that is what you require.
However, I feel in this case you may be asking the wrong question. As frames are usually the wrong approach.
When starting out in web design, frames seem like a great idea. You can seperate your navigation from your content, your site will load quicker because the navigation is not loaded every time and the menu is always visible, even when the page is loading.
But, actually, frames are incredibly bad for your usability.
Your users cannot bookmark individual pages
Printing is broken
Standard features in a browser like open in new tab often breaks
Users cannot copy/paste the web address for a specific page for sending to a friend
Frames do have their uses (e.g. Google image search), but for standard navigation menus they are not recommended. Try creating a page in a dynamic server language such as PHP or ASP.NET.
These languages have ways of creating standard elements such as your navigation menu without the use of frames.
No, this has nothing to do with CSS. CSS is for styling elements only. What you are looking for is an IFRAME. And IFRAME can be given a name
<iframe name="my_iframe" src="xyz.htm"></ifram>
and then be targeted in a link.
I've got a design that relies on framed content using CSS. You can do this by using overflow:auto, however it won't do what you want, i.e. loading certain portions of a page. To do this you'd need to use some AJAX library such as jQuery to load the content area dynamically. This is quite dangerous though as your URL may not relate to the current content of the page.
You could probably do something with the overflow part of CSS.
If you set up a div with overflow:auto with a fixed width and height with alot of content you will get scrollbars. Potentially you could use anchors to get content to move to be viewed within the div.
This means that all your content is in one page and it is just moved around with the anchors. You could do a similar thing using a jquery tabs plugin too.
I have never tried this and it might need javascript to get it to work fully.
