Forum Font Size Selector

[Ange TuteurAdministrator]

This plugin installs a small selector for the font size of the forum which allows you to adjust the size of the font to what you prefer.

Click to view demo

This plugin is optimized for the following forum versions :

• PhpBB3
  
• PunBB
  
• Invision
  

Note : This selector changes the global font size of the document and will not effect elements that have specified an absolute font size, such as text inside [size] tags.

Installation

To install this plugin go to Admin Panel > Modules > JavaScript codes management and create a new script with the following settings.

Title : Font Size Selector
Placement : In all the pages

Code:

$(function() {
  // font sizes
  var sizes = [
    8,
    9,
    10,
    11,
    12,
    13,
    14,
    15,
    16,
    17,
    18,
    19,
    20,
    21,
    22,
    23,
    24
  ],

  // position of the selector
  // 0 = top
  // 1 = bottom
  position = 0,
  attachTo = '#page-body, #ipbwrapper #content-container', // element(s) where the selector will be attached

  // language config
  lang = {
    Default : 'Default',
    FontSize : 'Font Size : '
  },


  cookie = my_getcookie('fa_fontsize'), // selected font size

  selector = $('<select id="fa_fontsize" />')[0], // font size selector
  container = $('<div id="fa_fontsize_container"><span id="fa_fontsize_label" style="font-size:12px">' + lang.FontSize + '</span></div>')[0], // selector container

  // options string
  html = '<option value="default:' + window.getComputedStyle(document.body, null).getPropertyValue('font-size') + '" ' + ( /default/i.test(cookie) ? 'selected' : '' ) + '>' + lang.Default + '</option>',

  // loop variables
  i = 0, j = sizes.length,

  // function for changing the font size
  change = function(init, val) {
    var value = init === true ? val : this.value;

    my_setcookie('fa_fontsize', value);

    document.body.style.fontSize = /default/i.test(value) ? value.replace(/default:/, '') : value + 'px';
  };

  // loop through the sizes array to create an options list for the selector
  for (; i < j; i++) {
    html += '<option value="' + sizes[i] + '" ' + (cookie == sizes[i] ? 'selected' : '') + '>' + sizes[i] + '</option>';
  }

  // apply the html and event handler to the selector
  selector.innerHTML = html;
  selector.onchange = change;

  // apply the chosen font size if any was selected
  if (cookie) {
    change(true, cookie);
  }

  // add the selector to the container and finally the document
  container.appendChild(selector);
  $(attachTo)[['prepend', 'append'][position]](container);
});

When you're finished and have saved the script, the font size selector should be available at the top of your forum. If not, please see the modifications section to find out how to modify this plugin.

Modifications

Below is a list of modifications that can be made to this plugin.


1. Sizes
At the top of the script you should see a variable named sizes. This variables contains an array of the font sizes available in the select drop down. Feel free to add more sizes or remove existing ones.

Code:

  var sizes = [
    8,
    9,
    10,
    11,
    12,
    13,
    14,
    15,
    16,
    17,
    18,
    19,
    20,
    21,
    22,
    23,
    24
  ],

Note : Please make sure to separate each number by a COMMA : , ( e.g. 1, 2, 3, 4 )


2. Position
Below the sizes array you should see the position variable. This variable takes two(2) values ; 0 and 1, and determines the position of the selector.
0 = The selector is placed at the top of the selected element
1 = The selector is placed at the bottom of the selected element

Code:

  // position of the selector
  // 0 = top
  // 1 = bottom
  position = 0,

Modify this variable to change the position of the font size selector.


3. Placement
Below the position variable you should see the attachTo variable. This takes a string of CSS selectors which determine WHERE the font size selector will be placed. By default its placed inside the forum body, however if you want it to display somewhere else, such as in a widget :

Code:

<div id="font_size_div"></div>

all you need to do is change the string so that it matches your element's id or class :

Code:

  attachTo = '#font_size_div', // element(s) where the selector will be attached

4. Language
Last but certainly not least is the lang object. You can use this object to change or translate the existing texts.

Code:

  // language config
  lang = {
    Default : 'Default',
    FontSize : 'Font Size : '
  },

That's all the modifications !

If you have any questions, comments, or find a bug feel free to leave a reply below. Enjoy !

Amazing tutorial, thanks @Ange Tuteur!!

[GuestGuest]

Thanks Ange.

Some people are color blind or have difficulties reading text in certain colors. Could you please introduce a modification to the script for members to select the color of their choice to be able to overcome that?

Good idea, It'd probably need another plugin. The only problem is that it wont be able to change all the text on the forum like this plugin does, so you'd probably need to include a selector set of the elements to modify.

Well, perhaps you could make it a color slider, just like the Night Mode slider. You may even want to create a floating menu which is visible on all the pages, like the bug reporter found on AvacWeb, and add all three of them to it: the Night Mode slider, the Color slider and the the Font Size selector...

Replace your code with:

Code:

$(function(){'DEVELOPED BY ANGE TUTEUR';'NO DISTRIBUTION WITHOUT CONSENT OF THE AUTHOR';'ORIGIN : http://fmdesign.forumotion.com/t571-forum-font-size-selector#8979';var sizes=[8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24],position=0,attachTo='#ipbwrapper #content-container',lang={Default:'Default',FontSize:'Font Size : '},cookie=my_getcookie('fa_fontsize'),selector=$('<select id="fa_fontsize" />')[0],container=$('<div id="fa_fontsize_container"><span id="fa_fontsize_label" style="font-size:12px">'+lang.FontSize+'</span></div>')[0],html='<option value="default:'+window.getComputedStyle(document.body,null).getPropertyValue('font-size')+'" '+(/default/i.test(cookie)?'selected':'')+'>'+lang.Default+'</option>',i=0,j=sizes.length,change=function(init,val){var value=init===true?val:this.value;my_setcookie('fa_fontsize',value);document.body.style.fontSize=/default/i.test(value)?value.replace(/default:/,''):value+'px'};for(;i<j;i++){html+='<option value="'+sizes[i]+'" '+(cookie==sizes[i]?'selected':'')+'>'+sizes[i]+'</option>'}selector.innerHTML=html;selector.onchange=change;if(cookie){change(true,cookie)}container.appendChild(selector);$(attachTo)[['prepend','append'][position]](container)});

Hello @Andrei34 thank you for your answer , you are referring to number 1 problem or number 2?

[Van-Helsing]

Hello @Skouliki,
For the first question add the above code in your css

Code:

#fa_fontsize_container {
    margin-top: -20px;
}

I think @Andrei34 is referring to the second question.

[skouliki]

Hello @Skouliki,
For the first question add the above code in your css

Code:

#fa_fontsize_container {
    margin-top: -20px;
}

I think @Andrei34 is referring to the second question.

thanks for your answer @Van-Helsing ..add it but nothing seems to move or change

problem 2 solved thanks @Andrei34

[Van-Helsing]

Hello @Skouliki,
In the first picture


the font container was down. After the code addition the font container moved up and justified with the search-box.

[skouliki]

Oh yes you are right!!! my fault then maybe i didnt explain well what i want
i want the resizer to be under or beside to the search bar

[Van-Helsing]

Well @skouliki find this css code

Code:

#fa_fontsize_container {
            margin-top: -20px;
        }

and replace the css for the font container with this:

Code:

#fa_fontsize_container {
    margin-top: -21px;
    float: right;
    margin-right: 240px;
}

the result will looks like this:

[skouliki]

@mrsrz

Note : This selector changes the global font size of the document and will not effect elements that have specified an absolute font size, such as text inside [size] tags.

It means that if you use absolute font sizes, such as "px", the font size selector will not affect it. See "Absolute Lengths" :
http://www.w3schools.com/cssref/css_units.asp

[mrsrzMember]

But there is no possibility of changing the sources of this element?
"div.tabla_contenido_acordes"

[Ange TuteurAdministrator]

No note unless you overhaul the script. The script only affects the default font-size of the body. If you use relative font-sizes for your elements, it'll work without issue.

[skouliki]

hello

I just noticed that nothing happens when i change the font size
It used to be ok as far as i can remember
Maybe a new java conflict? I usually add only your codes

Thanks

Hi @skouliki

Try replacing Ange's script with this one:

Code:

$(function() {
  'DEVELOPED BY ANGE TUTEUR';
  'NO DISTRIBUTION WITHOUT CONSENT OF THE AUTHOR';
  'ORIGIN : http://fmdesign.forumotion.com/t571-forum-font-size-selector#8979';
 
  // font sizes
  var sizes = [
    8,
    9,
    10,
    11,
    12,
    13,
    14,
    15,
    16,
    17,
    18,
    19,
    20,
    21,
    22,
    23,
    24
  ],
 
  // position of the selector
  // 0 = top
  // 1 = bottom
  position = 0,
  attachTo = '#page-body, #ipbwrapper #content-container', // element(s) where the selector will be attached
 
  // language config
  lang = {
    Default : 'Default',
    FontSize : 'Font Size : '
  },
 
 
  cookie = my_getcookie('fa_fontsize'), // selected font size
 
  selector = $('<select id="fa_fontsize" />')[0], // font size selector
  container = $('<div id="fa_fontsize_container"><span id="fa_fontsize_label" style="font-size:12px">' + lang.FontSize + '</span></div>')[0], // selector container
 
  // options string
  html = '<option value="default:' + window.getComputedStyle(document.body, null).getPropertyValue('font-size') + '" ' + ( /default/i.test(cookie) ? 'selected' : '' ) + '>' + lang.Default + '</option>',
 
  // loop variables
  i = 0, j = sizes.length,
 
  // function for changing the font size
  change = function(init, val) {
    var value = init === true ? val : this.value;
 
    my_setcookie('fa_fontsize', value);
 
    // forces font-size
    document.body.style.setProperty('font-size', /default/i.test(value) ? value.replace(/default:/, '') : value + 'px', 'important')
  };
 
  // loop through the sizes array to create an options list for the selector
  for (; i < j; i++) {
    html += '<option value="' + sizes[i] + '" ' + (cookie == sizes[i] ? 'selected' : '') + '>' + sizes[i] + '</option>';
  }
 
  // apply the html and event handler to the selector
  selector.innerHTML = html;
  selector.onchange = change;
 
  // apply the chosen font size if any was selected
  if (cookie) {
    change(true, cookie);
  }
 
  // add the selector to the container and finally the document
  container.appendChild(selector);
  $(attachTo)[['prepend', 'append'][position]](container);
});

Hope this helps ya.
