long story short,
here's my placeholder text:
<textarea id="colour" type="text" rows="9" name="message" placeholder="Hi, I'm the next star architect! Here's my work before ever studying for a RIBA1, I first got inspired into doing architecture playing Sims 4 and I instantly had to download Architecture software to build a house. My first project is my Mesuem/Art gallery and I grown massively in that first project. Please look though every project, especially the ones with the star. ... ...Also type here and hit send if you want to email me." ></textarea>
Hi=ow can I make the 'hi' part colour green or 'sims 4' part yellow without using the span tag,
is it even possible????
many thanks
didnt work.
No, it is not currently possible, and it is not best practices to use placeholder text to hold vital information. It would be much better to put your message around the input field or in a label, style as you wish, and keep placeholder text short and descriptive. Keep in mind not everyone can see your placeholder text and screen readers usually do not announce it.
If you would like more information on placeholder text and accessibility see the WCAG https://www.w3.org/WAI/tutorials/forms/instructions/#placeholder-text

In one of our native iPad apps, there's a screen divided into a number of sections. For the most part, I think it works well with VoiceOver. But one of those sections is a UIWebView that displays web content related to the app, but provided by another vendor. It's essentially a black box to us. So I have no control over what that content is (or how accessible it is), it's incredibly dense with little nuggets of content, and it's on the left side of the screen, so it comes before a lot of the other content in (English) reading order.
As a consequence, if I ask VoiceOver to read through the contents of the screen, it quickly gets bogged down in this web content, and I can't imagine many people sticking it out to the remainder of the screen. But making them give up and scrub the screen to discover things seems obnoxious.
What I would love to be able to do would be to have the read-through treat that whole region as a single unit and use a summary label or heading, but still allow the user to point into it or toggle it somehow to allow interaction with the web content. Is there any way to accomplish this on iOS (without completely confusing the accessibility system)?
Of course, I'm sighted, so I'm also acting on speculation to some extent. Would the current UI be as confusing to users relying on VoiceOver as I think? Is what I'm describing as my solution going to be an even worse situation?
aria-hidden="true" would make a screen reader ignore the whole content (if this screen reader is modern enough to take into account WAI-ARIA. VoiceOver is).
That isn't what you're trying to achieve I guess, and most of the time it isn't desirable: why would screen reader users not able to read the same content as others, who are you to decide for them what they can/can't read that other people can't/can? Except in known cases of complete inaccessibility like a keyboard trap and this keyboard trap can't be fixed for now
a skip link before this content would allow SR users to jump to the content that is after this section.
if relevant, known ARIA landmark roles would allow to choose which part of the page they want to read (it would need this section to be the whole sidebar - complementary role - or the main one. Probably not the case)
SR can navigate through headings (as well as links and sequential reading and now landmark roles).
If this section and the next one begin with good headings, then it can be bypassed quickly.
Relevant WCAG 2.0 Techniques:
Providing heading elements at the beginning of each section of content (H69)
Providing descriptive headings (G130)
Using h1-h6 to identify headings (H42)
Organizing a page using headings (G141)
If there's no heading element and it can't be modified, but there's some text that could've been a relevant heading except it's a paragraph or item list or whatever, it could be marked as an equivalent with ARIA by using role="heading" and aria-level="N" (see role="heading")
if you've a good reason to modify the natural reading order of columns (I think this is the case here), you can modify layout with floats and flexible box layout (IE10+) (latter has had 3 different syntax throught the years, plugins like autoprefixer are welcome, or SASS/Compass...). Your left column would then appear last when tabbing but that requires modifying the layout of maybe a lot of templates.
aria-describedBy can probably be useful in some way but I've not enough knowledge about its uses, maybe somebody else will know more about it.
From comments Sixteen said:
Unfortunately, like I said, I don't have any control over that content at all. It comes from elsewhere, and is being displayed by our app
I agree with Felipe. I don't know what your code looks like, but say this in basic HTML. You probably either embed the code with an iframe, or inject the content into your code (example PHP include()).
Regardless on the method you use, you probably wrap a <div> around it. So you could do
<div aria-hidden="true">
//iframe/inject here
</div>
to make it not be seen by AT. Taking this basic model, we could pull out aria-hidden="true" and replace with role="complementary". You could put text in the div, push it off screen and say a nice line, and same for aria-described by, but you may want to tack on tabindex to it. Ex:
<div aria-describedby="ex" tabindex="-1">
<p id="ex" class="offscreen">Below is useless jargon by blah blah blah. It may
be more beneficial to jump to the main section instead.</p>
//iframe/inject here
</div>
I'm developing for Windows Phone 8, I've designed my application and I noticed that there is an "Assignment grid" code that can be uncommented by default on a new project.
Take a look below for the description in the file:
<!--Uncomment to see an alignment grid to help ensure your controls are
aligned on common boundaries. The image has a top margin of -32px to
account for the System Tray. Set this to 0 (or remove the margin altogether)
if the System Tray is hidden.
Before shipping remove this XAML and the image itself.-->
<!--<Image Source="/Assets/AlignmentGrid.png" VerticalAlignment="Top" Height="800" Width="480" Grid.Row="0" Grid.RowSpan="2" IsHitTestVisible="False" />-->
This is the background image that shows when it is uncommented:
I'm confused by this, why are there "common boundaries" determined by an image? Surely the boundaries are determined within the development environment, IE the borders of the phone image? Even on that image shown above, the default "My Application" text doesn't fit within the "alignment image". So they're not abiding by their own alignment rule?
What am I supposed to take from this information? By keeping everything within these boundaries I'm going to be losing half of the screen space!
Why do I have to align my controls within these boundaries, will they end up not being shown? I thought the Windows Phones have the same resolution anyway?
EDIT:
I was hoping to put a notification button and indication of the current logged in username at the very top of my application like so:
The only way that I could have these inside the grid would be if I had them drooping down quite far, it wouldn't look how I want.
Should I definitely be putting everything within the grid image, if not am I heading for trouble with my implementation?
The grids are used as guidelines to make your app look aesthetically pleasing. If your text go all the way to the edges of the screen your app will look ugly. The grids between the boxes is used for aligning elements inside your app. You don't want all your elements to be all sticking together, they will look ugly. Windows Phone development focuses greatly on design.
Hope that helped!

I am trying to get a inputtext area and a submit button attached just to the right of it.
Ideally, the two together will use 100% of the width and be just side by side.
I have been trying to play around with ui-grid-a and similar options but everything fails miserably. You can see some attemps there. They are all equally ugly but the most complicated thing is to get the two elements side by side with one that has a fixed width (the button) and one that should take the rest of the width (hence neither fixed nor a percentage).
Do you have any idea how to render this properly?
In a dream world jQuery would have some built-in function to group those controls (just like <fieldset data-role="controlgroup" data-type="horizontal" data-role="fieldcontain"> for grouping checkboxes. But it does not seem so.
Thanks a lot for your help,

Hidden within jQuery Mobile's own documentation I found an approach that worked just fine for my search box + search button implementation.
In that page, they are comparing things side-by-side by using a simple <table> layout which inspired me to rely on this as well. While tables are NOT the go-to resource for doing layout/design well, it is extremely effective, simple, and circumvents many of the hassles of the workarounds I'm seeing here. Here is what my approach can do for your jsfiddle you linked. See the fourth iteration.
In other words, due to the complicated nature of how jQuery Mobile builds a page, adds in divs and styling that aren't in your markup, etc., this might be your best option for this particular scenario:
Wanting two columns of items where the second column is a fixed width.
Where the first column expands to fill the width of the screen on resize.
Where you want the elements to encompass the whole width of the device.
(Notably, if you wanted to tweak any of these particular aspects, some simple CSS padding or aligning should do the trick starting with this base solution)
<table style='width:100%'><tr>
<td>
<input type='text' (or type='search') />
</td>
<td style='font-size:80%; width:7em'>
<input type='submit' value='Submit' />
</td>
</tr></table>
Obviously, you should name and give an id to these items if you want to post them somewhere or manipulate them in javascript. Hopefully this proves helpful to someone else who is not put off by the nature of <table>s. I have been unable to see a downside to this approach using jQuery Mobile's simple interface / theming.
Lastly, you may want to stop and ask yourself if a submit button is even necessary. In mobile devices such as mobile safari, there is a button on the keyboard labeled "Go" whenever form input elements are being interacted with. This operates the same as a return key and can submit the search term. I have not vetted this option on other browsers at this time.
(This is not a solution to rival your approach to shift the icon of the search box. That is very clever but doesn't seem to be what your original question was about.)
I found a new answer for those of you that are looking at this thread.
I find it much better in terms of integration with jQuery Mobile. However, it could be vulnerable to upgrades in jQuery Mobile since it relies on how the icon image file is organized.
I simply added this CSS rule :
.ui-icon-searchfield:after {background-position: -252px !important;}
And the icon magically turns into a data-icon="check". Exactly what I was looking for! You can pick whatever icon you want by changing the offset and looking into images/icons-18-white.png for the icon mapping.
Of course you will want to refine the selector so you only target the input boxes you want to change.
Enjoy the hack.
the way I solved this problem was to float the input box next to the button, then have pagebeforeshow set the size of the input box to window width minus the size of the button.
After a fruitful discussion with adamdehaven, it turns out that:
A validate button is most of the time unnecessary and against the logic of mobile applications. It is better to use <input type="search" /> for such problems
The framework does not allow to customize the icon for type="search" content.
To make for the latter, I put together an ugly hack that you can see there. Unless you zoom in quite a lot you won't see a difference with the regular type="search" besides the darker grey. However, I suspect this solution could be vulnerable to minor changes to the framework in the future.
Another solution would be to directly pull out the icon and manually overimpose an home made icon button over the input. It should be slightly more robust (because at least the button would not be based on the framework) but requires a few quick photoshop changes to pull out the icon and put it in a propper file.
// my Question to the lovely lady in the corner
I would like to create a pagination for indicating what page is visible, like in iOS, (those little dots below a window, known as "page indicators" in the HIG.)
-- My project is hereby referred to as, Her Highness.
I found an example, but I can't find documentation on re-creating the layout, and it's in the experiment section :(
http://jquerymobile.com/test/experiments/scrollview/#../../docs/toolbars/footer-persist-a.html
I'm not sure why this is the part that seems hard to you, but if you're talking about how to make circles with html/css3, then I've got a simple answer. Just make your dots with a border radius equal to half the height/width.
<span class="dot dot1"></span>
<span class="dot dot2"></span>
<span class="dot dot3"></span>
<span class="dot dot4"></span>
...
.dot {
display: inline-block;
width:12px;height:12px;
border-radius:6px;
background-color:#8999A6;
}
.page4 .dot4 {
background-color: white;
}
If you can't figure out what to do beyond that, you're going to basically need someone to do the whole thing for you, but I'll give you a hint. Somewhere higher up, you're going to set a class indicating the active page. That will allow you to trigger CSS rules that could say which matching dot is active, and change the bg to white.
After reading the discussion under Russel's answer I think I understand what You want.
Create a presistent footer. That's not a trivial thing to do, but can be done.
You can take a look at my plugin for two column layouts http://jquerymobiledictionary.dyndns.org/dualColumn.html
or wait for me to take your issue into account while I work on it during the weekend (,which I advise you to :P).
After you got the presistent footer you can generate the dots from the list of pages and then handle a pageshow event to highlight the correct dot.
Wrapping the whole thing in a widget code would allow it to be a progressive enhancement, not a messy pile of code that would iritate users with nonAgrade browsers.
i have a flow panel that i'm adding extra items to it at runtime based on whether they have chosen to show all the items. that's all works fine; the expansion is controlled by a toolbar button.
the trouble is we'd like the user to be able to move his mouse over the "+" sign to expand the section.
initially i looked at TSpeedButton (OnMouseEnter) but even when it's "Flat", the focus rectangle still shows and so the glyph isn't centered. the main problem with this solution is it's appearance.
then i looked at making a descendant of TImage. that's a bit "unconventional" but it'd work. in OnMouseEnter or OnClick, it'd toggle an internal boolean "Expanded" flag and then load the appropriate picture from a resource. i have a dislike for unconventional solutions like that.
i need to add it to a few different screens so it's probably prudent for me to have/build a component for this. i have JVCL but i don't see anything suitable offhand.
thank you for your comments/help!
I always liked the approach used by the ModelMaker Code Explorer.
For example, when you're adding a new method, some rarely-used stuff is displayed collapsed ('Options and Directives' in the image below).
(source: 17slon.com)
When you hover over the text, you notice that it's actually a flat button. (Except that it's not - I believe Gerrit does some custom painting magic here).
(source: 17slon.com)
When you click this button, a panel appears. Button is still there, but with a new image. You can click it to close the panel.
(source: 17slon.com)
The state of this toggle button is preserved between sessions. IOW, even if you restart the Delphi, next tima you invoke 'Add Method', the 'Options and Directives' panel will appear exactly as you left it the last time.
i have a dislike for unconventional solutions like that.
Over the past few years, I have grown a bit suspicious of unconventional UI solutions — which is what you seem to be creating here. Why not just use a button that the user actually has to click? That seems to be much more common in the software I use, be it MS Office or programming utilities. Also, I'd make the button somewhat larger: in the screenshot, it really seems like a tiny little thing you have to target with your mouse cursor. Oh well, and if I'm bugging you with advise you haven't asked for anyway, why not give it ">>" as a caption instead of "+"? And if you'd give it a textual caption with a mnemonic as well, it'd actually be keyboard accessible. All this should make your UI better and more intuitive. I guess.
I do apologize for not answering your question, but I hope you'll spend 2 minutes thinking whether your users would actually prefer this solution :-)
Good luck!
Actually, I think that using a TImage in this situation is pretty conventional. I have seen many people suggest using the TImage, when either the TButton, or any of its associates did not have the right amount of control for whatever the developer was trying to do.
Have you tried a TBitBtn? I think when you get rid of the text it centers whatever image you have associated with it. I just checked in Delphi 6, all I have installed on this machine, and it had the MouseMove event.
