• czysty CSS dla pojedynczego znaku
• JavaScript używany do automatyzacji tekstu lub wielu znaków
• zachowuje dostępność tekstu dla czytników ekranu dla niewidomych lub wizualnych zaburzenia

Część 1: Podstawowa Rozwiązanie

Demo: http://jsfiddle.net/arbel/pd9yB/1694/

Działa to na dowolnym dynamicznym tekście lub pojedynczym znaku i jest zautomatyzowane. Wszystko, co musisz zrobić, to dodać klasę do tekstu docelowego, a reszta jest załatwiona.

Również dostępność oryginalnego tekstu jest zachowana dla czytników ekranu dla osób niewidomych i słabowidzących.

Wyjaśnienie dla pojedynczego znaku:

Czysty CSS. Wszystko, co musisz zrobić, to zastosować klasę .halfStyle do każdego elementu, który zawiera znak, który chcesz mieć w połowie stylizowany.

Dla każdego elementu span zawierającego znak, możesz utworzyć atrybut data, na przykład tutaj data-content="X" , a na pseudo elemencie użyj content: attr(data-content);, więc klasa .halfStyle:before będzie dynamiczna i nie będziesz musiał jej kodować dla każdej instancji.

Wyjaśnienie dla dowolnego tekstu:

Wystarczy dodać textToHalfStyle klasę do elementu zawierającego tekst.

// jQuery for automated mode
jQuery(function($) {
    var text, chars, $el, i, output;

    // Iterate over all class occurences
    $('.textToHalfStyle').each(function(idx, el) {
    $el = $(el);
    text = $el.text();
    chars = text.split('');

    // Set the screen-reader text
    $el.html('<span style="position: absolute !important;clip: rect(1px 1px 1px 1px);clip: rect(1px, 1px, 1px, 1px);">' + text + '</span>');

    // Reset output for appending
    output = '';

    // Iterate over all chars in the text
    for (i = 0; i < chars.length; i++) {
        // Create a styled element for each character and append to container
        output += '<span aria-hidden="true" class="halfStyle" data-content="' + chars[i] + '">' + chars[i] + '</span>';
    }

    // Write to DOM only once
    $el.append(output);
  });
});

.halfStyle {
    position: relative;
    display: inline-block;
    font-size: 80px; /* or any font size will work */
    color: black; /* or transparent, any color */
    overflow: hidden;
    white-space: pre; /* to preserve the spaces from collapsing */
}

.halfStyle:before {
    display: block;
    z-index: 1;
    position: absolute;
    top: 0;
    left: 0;
    width: 50%;

Część 2: zaawansowane rozwiązanie-niezależne od lewej i prawej części

dzięki temu rozwiązaniu można stylizować lewe i prawe części, indywidualnie i niezależnie.

Wszystko jest takie samo, tylko bardziej zaawansowany CSS robi magię.

Część 4: gotowe do produkcji

Dostosowane różne zestawy stylów mogą być używane na pożądanych elementach na tej samej stronie. Możesz zdefiniować wiele zestawów stylów i powiedzieć wtyczce, którego z nich użyć.

Więc po prostu na elemencie zawierającym tekst dodaj textToHalfStyle klasę i atrybut danych data-halfstyle="[-CustomClassName-]". Wtyczka wykona resztę pracy.

Również definicje klas CSS style-sets pasują do [-CustomClassName-] części wymienionej powyżej i są przykute do .halfStyle, więc będziemy mieli .halfStyle.[-CustomClassName-]
