There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.

ここでデモをチェックできます：http：//easwee.net/floated_img_article/
問題： 画像は2つの異なる幅（3：2の比率-水平または垂直）を持つことができます。ご覧のとおり、見出しには背景画像があり、フロート画像の背後にあります。
見出しのテキストが始まるところから背景画像を開始するcssソリューションはありますか？それにより、フロート画像と重ならないようになりますか？左の丸い角が見える必要があります。
PS：javascriptソリューションを紹介することもできますが、これはcssで解決したいと思います。
