私が探しているもの:
文字の半分をスタイル設定する方法。(この場合、文字の半分は透明になります)
現在検索して試してみたもの(運なし):
- 文字の半分をスタイリングする方法
- CSS または JavaScript を使用して文字の一部をスタイリングする
- 文字の50%にCSSを適用する
以下は私が取得しようとしているものの例です。
これに対する CSS または JavaScript ソリューションは存在しますか、それとも画像に頼らなければなりませんか? このテキストは動的に生成されることになるため、画像ルートは使用したくないです。

- 1文字分の純粋なCSS
- テキストまたは複数の文字にわたる自動化に使用される JavaScript
- 視覚障害者向けのスクリーンリーダーのテキストアクセシビリティを維持します
パート1: 基本的な解決策
デモ: http://jsfiddle.net/arbel/pd9yB/1694/
これは、あらゆる動的テキスト、または単一の文字で機能し、すべて自動化されています。必要なのは、ターゲット テキストにクラスを追加することだけです。残りは自動的に処理されます。
また、視覚障害者向けのスクリーンリーダー向けに、元のテキストのアクセシビリティも維持されます。
1文字の説明:
.halfStyle
純粋な CSS。半分スタイル設定する文字を含む各要素にクラスを適用するだけです。
文字を含む各 span 要素に対して、たとえばここでデータ属性を作成し、data-content="X"
疑似要素で使用するcontent: attr(data-content);
と、.halfStyle:before
クラスが動的になり、インスタンスごとにハードコードする必要がなくなります。
テキストの説明:
textToHalfStyle
テキストを含む要素にクラスを追加するだけです。
// 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

パート2: 高度なソリューション - 左右の独立した部分
このソリューションを使用すると、左側と右側の部分を個別に独立してスタイル設定できます。
すべては同じですが、より高度な CSS が魔法をかけているだけです。
