css - webkit 上的-moz-background-inline-policy

Question

Webkit 中是否存在类似-moz-background-inline-policy 的东西？该属性基本上让您有机会指定如何为内联元素的每一行呈现背景。我在不同的浏览器上附加了相同元素的图像。

这是在 firefox 上的结果(使用 -moz-background-inline-policy: each-box;)

这是在 Google Chrome 上的(我试过 -webkit-background-inline-policy，但它似乎不存在)

更新

由于 Webkit 上没有后台策略属性，我正在尝试使用 jQuery 寻找不同的解决方案。我在每行文本后面添加了一个额外的跨度。没关系，除了文本没有正确测量这一事实。您可以在此处查看两个示例:

1. 原方案(后台内联策略):http://jsfiddle.net/notme/mCnGy/5/
2. 新解决方案(jQuery 跨度):http://jsfiddle.net/notme/my3br/1/

            lineText += text[i];
        }

        lastTopOffset = topOffset;
    }
    lines.push(lineText);

    this.html(openTag + lines.join(closeTag + openTag) + closeTag);
    dummy.remove();
};

//thanks @thirtydot
var fixIt = function() {
    //remove previous .dummy
    $('.dummy').remove();

    $('div.node-title-text').each(function(index) {

        var dummy = $(this).clone().removeClass().addClass('dummy').appendTo($(this).parent());
        console.log(dummy);
        $(dummy).wrapLines('<span><span>', '</span></span>');

        var padding = 15;

        dummy.css({
            left: -padding,
            right: -padding
        }).find(' > span').css('padding-left', padding*2);

    });
};

$(window).load(function(){
    $(window).resize(fixIt).resize(); //trigger resize event onLoad
});

这行得通，但它可能会变得更有效率:

        }

        lastTopOffset = topOffset;
    }
    lines.push(lineText);

    this.html(openTag + lines.join(closeTag + openTag) + closeTag);
    dummy.remove();
};

var fixIt = function() {
    $('.dummy').remove();

    $('div.node-title-text').each(function(index) {
        //remove previous .dummy
        var dummy = $(this).clone().removeClass().addClass('dummy').appendTo($(this).parent());
        $(dummy).wrapLines('<span><span>', '</span></span>');
    });
};
$(window).resize(fixIt).resize(); //trigger resize event onLoad

CSS:

.node-title {
    position: relative;
    margin-bottom: 16px
}
.node-title-text {
    position: relative;
    z-index: 2
}
.dummy {
    position: absolute;
    top: 0; left: 0;
    z-index: 1
}
.dummy > span {
    background: url('http://i.stack.imgur.com/HPofR.png') top left no-repeat,
        url('http://i.stack.imgur.com/C8ImH.png') top right no-repeat,
        url('http://i.stack.imgur.com/9is9r.png') top center repeat-x;
}
.dummy > span > span {
    visibility: hidden
}
