46 | CSS and Javascript to display Braille
47 |
48 |
49 | This library offers some CSS and Javascript to display Braille in web pages (for sighted people).
50 |
51 | With the CSS you can easily display Braille characters. With one CSS class name for every Braille character, you can display Grade 1 Braille.
52 |
53 |
56 |
57 | 3 styles of Braille:
58 | big -
59 | small -
60 | small 3d
61 |
62 |
63 | Javascript to make it dynamic.

83 | The goal of this project is to introduce sighted people to the Braille system. It doesn't help with screen readers and is not intended for serious Braille transcription.

The CSS using a picture containing all characters (for faster loading). It needs to be included with the CSS.
139 |
140 | Notes: "br" is the grade 2 abbreviation of "Braille".
141 |
142 |
143 | Installation
145 |
146 | First, load CSS file (braille-big.css or braille-small.css).
147 |
148 | <link href="css/braille-big.css" rel="stylesheet" type="text/css">
149 |
150 |
151 |
152 | You may not need to include the Javascript. If you do, use the following:
153 |
154 | <script src="braille-tools.js" type="text/javascript" charset="utf-8">
155 |
156 |
157 |
158 |
159 |
160 | ABC
162 |
163 | Using the CSS classes in your HTML, you can display Braille.
164 |
165 |
166 |
167 |
168 |
169 | HTML:
170 |
171 | <div class="br br-cap">
172 | <div class="br br-a"></div>
173 | <div class="br br-b"></div>
174 | <div class="br br-c"></div>
175 |
176 |
177 |
178 |
179 |
180 | Hello World
182 |
183 |
186 |
187 | Javascript:
188 |
189 | document.write(br.braille('Hello World'))
190 |
191 |
192 |
193 | It can also be use with longer text:
194 |
201 |
202 | Javascript:
203 |
204 | var txt = 'Braille is a means of reading and writing for blind people. '+
205 | 'The Braille system was invented by Louis Braille. He has made it '+
206 | 'possible for blind people to take notes, write letters, read books and popular '+
207 | 'magazines, compute mathematical equations, and even read and write music.';
208 |
209 | document.write(br.braille(txt))
210 |
211 |
212 |
213 |
214 | Alphabet
216 |
217 |
220 |
221 | Javascript:
222 |
223 | document.write(br.alphabet())
224 |
225 |
226 |
227 |
229 |

243 | <div id="myBraille" class="braille"></div>
244 |
245 |
246 |
Javascript:
247 |
248 | function showBraille() {
249 | var message = document.getElementById("txtBraille").value;
