Adjusting the CSS of an element based on varying languages

Is it possible to utilize CSS for text styling based on the language being used?

For instance, the font Tahoma is commonly used for Arabic text, but its size may appear extremely small when applied to English text of the same size.

Therefore, in scenarios where there is English text within Arabic text, is there a method to automatically recognize the switch in language and adjust the font size accordingly for the English text embedded in the Arabic one?

Thank you.

Answer №1

There isn't a built-in CSS solution for this specific task, but you can experiment with iterating through each text node in JavaScript and checking for alphabetic characters without case sensitivity (match(/^[a-z]+$/i)). Keep in mind that this method won't guarantee the language is specifically English.

If the condition is met, you can assign a custom class to the parent element, such as appears-english, and then style it using CSS properties like

.appears-english { font-size: 120% }
.

Update

Upon request, below is a sample code snippet...

JavaScript

var divs = document.getElementsByTagName('div');

for (var i = 0, divsLength = divs.length; i < divsLength; i++) {
  var div = divs[i];

    if (div.firstChild.nodeValue.match(/^[a-z]+$/)) {
       div.className += 'appears-english';
    }  

}

CSS

.appears-english {
   font-size: 170%;  
}

jsFiddle.

The provided fiddle demonstrates that numbers are not matched - you can modify the regex to include numbers, letters, and underscore by changing [a-z] in the regex to \w.

Additionally, if you need to update English characters within an element that also contains Arabic characters, consider using replace() and wrapping them in span elements assigned with the appears-english class.
