Buttons to add/remove contrast and increase/decrease font size.

Read in other languages.

🇧🇷

Install

npm install accessibility-buttons --save

Usage

Import

• accessibility-buttons/dist/css/accessibility-buttons.css
• accessibility-buttons/dist/js/accessibility-buttons.js

Add buttons

<button type="button" data-accessibility="font">+A</button>
<button type="button" data-accessibility="contrast">Add Contrast</button>

Initialize after DOM ready

accessibilityButtons()

Note: Note: Font size works only with em or rem units.

Settings

To set up buttons names and aria-labels, use the following parameters.

// default values
accessibilityButtons({
    font: {
        nameButtonIncrease: '+A',
        ariaLabelButtonIncrease: 'Increase Font',
        nameButtonDecrease: '-A',
        ariaLabelButtonDecrease: 'Decrease Font'
    },

    contrast: {
        nameButtonAdd: 'Add Contrast',
        ariaLabelButtonAdd: 'Add Contrast',
        nameButtonRemove: 'Remove Contrast',
        ariaLabelButtonRemove: 'Remove Contrast'
    }
})

Font size and contrast colors could be customized only overwritting class values.

Example:

body {
    font-size: 1em;
    color: #a9a9a9;
    background: #000;
}

body input,
body textarea,
body select,
body button {
/* The default font-size of these elements is approximately 20% less than the body */
  font-size: 0.9em;
}

body.accessibility-font {
    font-size: 1.5em;
}

body.accessibility-font input,
body.accessibility-font textarea,
body.accessibility-font select,
body.accessibility-font button {
/* The default font-size of these elements is approximately 20% less than the body */
  font-size: 1.2em;
}

body.accessibility-contrast {
    color: #000;
    background: #a9a9a9;
}

Extend use with data attribute or class

Hi Tiago!
I hope you are super well,
First of all! Thank you. I'm using your script accessibility buttons, which is excellent.
I would like to know if you could help me with something:
I'm trying to extend the functionality to other elements like data-* or class.
Why? Simple what if i need to put a button in a header and footer or some dummy esthetic thing :P ?
Use the same ID atrib, is like all know, invalid. Both, for the W3c and for all screen readers.
That's why i'm trying to replace the use of the ID by a data-id or class,

I made some adjustments but with no luck. I leave you the Pastebin

Another cool stuff would be use a valid role="switch".

Thank you very much!

Does it only shows the buttons?

IE Edge Issue: SCRIPT16389: SCRIPT16389: Unspecified error.

I am getting an error in IE Edge that "SCRIPT16389: SCRIPT16389: Unspecified error." It's working on all the browsers except Microsoft Edge.

This is my code:

App.controller('home', function(page){

	   if(typeof localStorage !== "undefined"){
		   if (localStorage.getItem("reciepent-list") !== null) {
              
              //var reciepentList = JSON.parse(localStorage.getItem("reciepent-list"));
			   var reciepentList = localStorage.getItem('reciepent-list') ?
				   JSON.parse(localStorage.getItem('reciepent-list')) : 
          [];
              
              $.each(reciepentList, function( index, value ) {
                
                  $(page).find("#contactList").append('<div class="app-button redirect">' + value + '</div>');
            
              });
              
              $(page).find("#contact-list").show();
              
              $(page).find(".redirect")
                  .clickable()
                  .on("click", function() {
                  
                  localStorage.setItem("to", $(this).html());
                  
                  App.load('sendEmail');
                  
                  
                  
              });
              
              
          } else {
              
              $(page).find("#contact-list").hide();
              
          }
          
	   }
	   
	 
   });
	
   App.controller('sendEmail', function(page){
	   //alert("sendEmail loaded");
	   
	   if(typeof localStorage !== "undefined"){
		   
		  if(localStorage.getItem('from') !== null){
			  $(page).find('#from').val(localStorage.getItem('from'));
		  }
		   
	   }
	   
	   
	   
	   $(page).find('#send').
	   clickable().on('click',function(){
		   
		   if(typeof localStorage !== "undefined"){
			   localStorage.setItem('from',$('#from').val());
			   
			   var reciepentList = new Array();
			   
			   if(localStorage.getItem('reciepent-list') !== null){
			   
			   reciepentList = JSON.parse(localStorage.getItem('reciepent-list'));
			   }
			   
			   if($.inArray($('#to').val(),reciepentList) == -1){
				   reciepentList.push($('#to').val());
				   reciepentList.sort();
				   localStorage.setItem('reciepent-list',JSON.stringify(reciepentList));
				   //alert("in array");
				   console.log(reciepentList);
			   }
			   
		   }
		   else{
			   alert("Email data couldn't be saved");
		   }
		   
	   })
	   
	 
   });
  
   
	
   try{
	   App.restore();
   }
	catch(err){
		App.load('home');
	}

I am getting error in these two lines of code:

   if(typeof localStorage !== "undefined"){
		   if (localStorage.getItem("reciepent-list") !== null) {

How to solve this issue. Any help would be highly appreciated.

Broke when use just one button

I found a bug that when i use just one button the program bugs

Botões de Constraste

Fala Tiago, primeiro parabéns por essa iniciativa muito legal queria deixar uma dica pra você.

Não utilize o atributo title na tag pois nos leitores de tela isso tornara uma informação repetida e para um usuário que não enxerga isso mais atrapalha do que ajuda.

Recomendo utilizar o aria-label resolveria o problema, no caso do botão de aumento e diminuição de fonte, agora o botão de constraste não vejo necessidade porque ele é auto declarativo ele explica o propósito dele.

Lembrando que o atributo aria-label que faz parte da WAI-ARIA já é recomendação da W3C e pode ser usado e o NVDA, JAWS 13 e VoiceOver já interpretam ele, bom espero ter ajudado.

Abraço.

Validation for subject and message field is not working

I am creating an email app. First fill the from and to fields and then when click send that links via Ajax to a php script which then sends the e-mail and returns true and the app interprets this as a successful send. It will also validate the form before sending and the recipient email addresses which are used automatically appear in the email address list.

Everything is working except the subject and message. The validation for a subject and message is not working, even it's sending the mail without subject and message.

I have attached two files. Please go through the code.

Any help would be appreciated.

Thanks
