This cannot be done in CSS, due to the fact that CSS only alters the presentation of HTML, not the underlying data or attributes. Therefore JavaScript is your only solution in this case. To that end I'd suggest:

// retrieving all elements with a title-attribute, using
// document.querySelectorAll(), and converting that into an Array
// using Array.from.
// we then use Array.prototype.forEach() to iterate over each of
// those nodes:
Array.from(document.querySelectorAll('[title]')).forEach(function(el) {
  // 'el' (the first argument) is the current Array-element of the
  // Array over which we're iterating.

  // here we use String.prototype.replace() to replace a the
  // captured string `[a-z]` (lower-case only) which follows a
  // a word-boundary (`\b`) finding all matches (g) from the supplied
  // string, and using the anonymous function of the replace() method:
  return el.title = el.title.replace(/\b([a-z])/g, function(m){

    // here we return the match ('m') once we've converted it
    // to uppercase using String.prototype.toUpperCase():
    return m.toUpperCase();

Array.from(document.querySelectorAll('[title]')).forEach(function(el) {
  return el.title = el.title.replace(/\b([a-z])/g, function(m){
    return m.toUpperCase();
a::before {
  content: attr(title);
<a href="#" title="this is title in lowercase"></a>
