Is there any alternative to <div>? My website is losing "accessibility" because I cannot set focus on a <div>. What control should I use in order to replicate <div> and still hold focus?
This is what my HTML looks like:
<div style="height:70px; overflow:hidden" id="divMsg">
<div class="DivClass">abcdefg abcdkfjghfjdfkj</div><br>
<div class="DivClass">abcdefg abcdkfjghfjdfkj</div><br>
</div>
You can add tabindex to make it focusable; however, this is usually not enough. If you want the element to be clickable, you will also need to add a keydown or keypress handler so that the user can activate it using ENTER, similar to a A link. Otherwise the user will be able to tab to it, but may not be able to do anything with the link after.
If you are trying to create a clickable element, it is sometimes simpler to start with a A tag, and then style it so that doesn't look like a link. A elements respond to both keyboard and mouse and fire onclick for both, so you don't have to do additional keyboard input handing like you do with a DIV.
Finally, if you are making a DIV or A that visually looks like a button or some other control, add the appropriate ARIA role so that a screenreader will call out the appropriate element type - eg.

Just give it a tabindex attribute.
If you are specifically looking for accessibility, try out the new HTML 5 tags like <article>. So for example a textreader knows what to read, and your page is much better structured.

To answer your exact question, it depends why you are using the div; I'm guessing for layout. The tab ordering is dependent upon more than tabindex, as defaults and overflow affects positioning and focus.
To be more specific, you won't use a div to latch onto for tabindex. Rely upon JavaScript and a unique ID; <div class="content" id="page1">
This will also provide you an anchor so you could use http://index.html#divMsg to link focus to the exact place in your HTML document. Note you have only one div ID and reuse the same div class twice in your example.

Links (element a) and form elements (input text and alike, file, radio and checkbox, submit, image and type button, select, textarea, button element, etc) are focusable by default.
Thumb rule: if an element does something, it should be a link or a form element part of a form. (OT: I guess I've a problem with conjugation here but can't find exactly what - english isn't my mothertongue)
Think twice (at least :)) before using the tabindex attribute: it'll work for a while in your project and then you make some modification elsewhere and suddenly all is broken. And it'll break again, again and again.
For testing with Safari, you'll need to modify Preferences: this browser (maybe also Chrome?) only cycle by default through form elements and not links. Users of keyboard cycle through every focusable elements I guess, like in IE and Firefox.
To learn further, Web Content Accessibility Guidelines 2.0 (WCAG 2.0) have Sufficient Techniques (and "Failure(s)" also) about keyboard use.

I am building an app which has to be WCAG compliant. It requires about 12 buttons. Some of the buttons have only tooltips and icons but no labels. I haven't been able to find clear cut language in WCAG about this problem. Are titles necessary for buttons?
Short answer
Yes, your button must have so form of text label associated with it.
But don't be confused with <label>, which is normally unneeded for a button.
Long answer
The answer isn't answered directly in WCAG, but this is a question of perception, which is the first WCAG core principle.
If your button has only an icon but no alternative text or label, it follows that screen reader users won't perceive your button.
So, in the broad sense, yes, your button must have a kind of label.
You have several ways to set an accessible label, technically known as accessible name, to a button having no text itself:
Attribute alt of <input type="image"/> or the <img/> which is inside the button
aria-label or aria-labelledby attributes
Visually hidden text
Don't be confused with <label> element. It's unneeded for a button, since a button usually carry its own accessible name.
An <input type="text"/> need a separate <label> because it has typically no accessible name otherwise.
This may also be a question of understandability, which is the second WCAG principle.
Even for perfectly sighted people, are you sure that the meaning of your button without any text is crystal clear ? Few icons are known to be almost universally understood by everybody without any hint, any help, any tooltip, nothing.
IN that quite small list you can certainly find multimedia buttons (play/pause/stop/record), parameters/settings wheel, power on/off, but probably not many more.
As a consequence, the question isn't only about having an accessible name for screen readers. It goes much beyond that.
To wrap up, yes, your button definitely must have some form of text label associated with it.
Short Answer
You should add aria-label to your buttons.
Longer Answer
Buttons need a name that can be computed for accessibility. First to answer your questions:
Are titles necessary for buttons?
No
Should buttons have labels from WCAG point of view?
No once again, in fact they are probably not valid.
So what should I do?
Buttons don't need titles or <label>s (in fact a <label> on a button would probably not be valid without some WAI-ARIA).
But, they do need to have an accessible name, and I think this is the part that is causing confusion.
Because your buttons only have an icon and a tooltip, they probably / possibly do not have any text that is useful to assistive technology (such as a screen reader).
So when they reach a button with just an icon using a screen reader they will hear "button", with no indication of what the button is for!
The fix
There are several ways to approach this, but the easiest is aria-label.
WAI-ARIA is a set of attributes you can add to HTML elements to add extra meaning / semantics to make a page make more sense to assistive tech users.
The aria-label attribute, when used on an interactive element (such as a button, an anchor / hyperlink etc.), will indicate the the browser "hey, please present this as the accessible name for this element.".
So in your example, something similar to the following would ensure that the purpose of a button is clearly described:
<button aria-label="Add New Document">
<!-- your icon -->
</button>
So instead of just saying "button" when focused it will now say "Add New Document, button".
In terms of accessibility, can someone describe to me the difference between a <button> and a <a> for screen reader and keyboard users? From what I can tell a keyboard user can use ENTER and SPACE to activate a button, whereas only ENTER for an anchor tag. In a Single Page Application I feel like the roles of these elements get somewhat confused and I'm not sure where the line draws between the two.
Buttons that look like links
In my application I have a generic styling for a link, the class name for this is simply .link.
In the first example I have a button with an onclick handler that performs an action on the same page, therefore I've used a button element for it. However it stylistically looks like a link.
<button class="link" onclick={(e) => console.log('Do the thing')}>This is a link</button>
If the roles are reversed and the link behaves like a traditional anchor where the route changes as a result of it being clicked, I'd do something like this:
<a class="link" href="/route/change">This is a link</a>
Even though both of these look the same due to the applied class, should the anchor tag example have role="button" applied so it behaves like a button even though it's styled like a link? Is it better to maintain consistency between these styled elements for users with accessibility needs throughout the entire application, or is it better to interchange which gets the role applied to it based on the application of the element regardless of how it's styled.
Two "buttons" next to each other
Following up on the first question. If the definition of an <a> tag is that it moves you to a different page/anchor point, should two side by side buttons which perform different tasks both be considered buttons.
Taking the following example, the confirm button performs an action on the same page, and the cancel button routes you back to the previous page.
The code looks something like this:
<button onclick={() => console.log('do a thing'}>Confirm</button>
Cancel
The definition of role="button" from MDN says the following:
The button role should be used for clickable elements that trigger a
response when activated by the user. Adding role="button" will make an
element appear as a button control to a screen reader. This role can
be used in combination with the aria-pressed attribute to create
toggle buttons.
Should the cancel button have the button role applied even though it's technically not behaving in the way of the roles definition?
Closing
Is there more concise guidelines on when these roles should and should not be used? Is there any harm in applying role="button" to any/all links that use the same styling if they are used interchangeably with the <button> element? Or should anchor tags and roles never mix, regardless if they stylistically look like another element type?
I appreciate you for reading. I'm attempting to take accessibility seriously but can't seem to find any clear and concise specifications surrounding use cases for this scenario.
Whenever i get this question of Buttons vs link I ask myself, is it scripted functionality or a is it Navigation(internal or external)?
Buttons activate scripted functionality on a web page (dialogs, expand/collapse - regions).
Links take you to another location, either to a different page or different location on the same page.
Coming to a11y
Role tells screen readers and other assitive technology the semantic category of an element, meaning the type of thing that it is. Every element already has a default role of some kind. The <button> element has an implied role="button", and the <img> element has an implied role="img" and so on.
role="button"
if you use <button> don't add role (it's implicit)
<div role="button"> - (Adding roles do not cause browsers to provide keyboard behaviors or styling). Try to use real <button> If that’s problematic for styling purposes, you can use role="button". Be sure to add tabindex="0" to make it keyboard focusable, and ensure it works with both the Enter key and Spacebar, ensure it has proper disabled, hover, focus state, works in high contrast using media query.
Don't use <a role="button"> : it doesn't make sense in any way, it'll give you a block element just like <div> which you can style anyway, remember the question, it is a scripted functionality use
<button> or <div role="button"> , if it is a navigation use
<a> without any role (style it the way you want)
Also, <a> cannot be disabled, <buttons> can be.
Screen readers have shortcuts to read out all the links eg NVDA user can press
K - jumps to Next link
INS + F7 it lists all links, headings
U Un visited Link Quick Key
V Visited Link Quick Key
I also think about do I want screen reader users to hear this link when they press ins + f7 ?
EDIT: I missed to mentions assigning a role to an element overrides its native role. so <a role="button" is no more a role="link" and won't come up in INS + f7 list and as it will be treated by the accessibility API as a button
In this particular case I would recommend to use role='button' on the link since it's one of two choices the user has in this situation, and the two choices should appear in the same form (i.e. as two buttons), also for a user who hears it being read by a screenreader.
I just wonder why you use a link for the cancel option in the first place, and not a button right away...
The solution is easy : "If it's not a link, it's a button"
A link should drive you somewhere else : another page, another anchor within the page.
A link does not submit a form, does not perform any action.
In your example, "Confirm" and "Cancel" are actions : you're submitting your consent or explicitly indicating your desire to cancel your action. They should have the ARIA button role.
This is a different from "Continue" and "Back to the previous" page, which should have the link role.
I have an IMG tag which has an associated OnClick event.
I see that TAB-key navigation skips this image field, but I need to have it stop there and treat the element as a regular tabbable control field.
Is there a way to do this? I can't just wrap a simple A-tag around it, since that affects various stylesheets and breaks the design.
In general, the best approach is to use a button instead, and bind the click event to that.
<button type="button"><img src="..." alt="..."></button>
You can also stick tabindex="0" onto the image so that it will appear in the tab order (without specifying a specific place so the ordering is natural), but this doesn't give as good results with AT.
I have a website and I'm making it available for keyboard users. This might have been asked before but I haven't found a way to make it work yet. :(
The issues that I'm having is that on a certain point there is a slideshow and a pauze/play link. When a users tabs through the site, he first has to go through the entire slideshow and then the focus lands on the pauze/play link.
I've tried recreating it as best and simple as possible.
Fiddle here
When you tab through the elements you notice that the focus goes directly on the slides and afterwards goes to the pauze/play link. I know this is normal behaviour because of the HTML structure.
My question is: How can I manipulate this order that whenever I tab from the last "link" the focus goes straight to the pauze/play instead of going to the slides.
I've tried messing around with tabindex="0 / 1"; but then I need to put this on all the elements?
(sidenote: on the website are a lot more HTML elements above this 'slideshow' and I cannot change the structure that is given)
Thanks in advance!
The only way to change this order is to reorder your HTML elements.
tabindex itself can do 2 things:
it sets the order of "focusable" elements
it makes element "focusable".
tabindex = -1 Element will not get focus
tabindex = 0 Element will be focusable in the normal tab (semantic) order
tabindex = 1 Element with positive values will be focused first
There is no way to change the tab selection without using tabindex (or JavaScript).
jsfiddle
I have some HTML DOM elements for which I need to capture click events, like a drop-down menu widget, etc.
I guess we can implement in 2 ways:
My text
or another way is:
<span id="option2">My text 2</span>
In the second option, of course I can add CSS property cursor:pointer.
All I need is to capture the click event, for which I can have the same click handler function for both the cases.
Do you think there is any reason why we would use anchor tag method?
The second option looks more clean. Also, the IE has a default behavior for anchor tag click events, which can have unwanted consequences, etc.
Some benefits of the anchor tag:
you can provide a default behavior for users who don't have JavaScript enabled (if you care about that).
tabbing on the keyboard will set focus on anchor tags by default.
you get default styles that may be desirable on anchor tags.
Depends on what you need/want. Using links have the benefit they will be displayed as links (other color, different mouse cursor, possibility to search only for links, maybe accessibility issues, etc.)
Using spans does not do this but has other benefits like no different color if you activated or visited the link already.
That being said there is IMHO no real benefit for choosing either method probably depends if the text should be displayed/behave like a link or not.
For span look like an anchor you have to setup colors (standard and hover. And there'is no way to set Visited for it), underline and cursor:pointer. Still think it's cleaner?
