Question

有没有办法为菱形文本块创建标记，其中每个新行都偏离前一个。

我找不到任何解决方案。可能为此我需要一些javascript。

Answer 1

据我所知，此时没有跨浏览器 css方式来执行此操作。所以我戴上了创意帽并为你写了一些东西。

function rhomboit(obj, offset) {
    var invert = false;
    if(offset < 0){
        offset = Math.abs(offset);
        invert = true;
    }
    var line_height = getLineHeight(obj);
    var els = document.querySelectorAll('.rhombus_side');
    for (var i = 0; i < els.length; i++) {
        els[i].parentNode.removeChild(els[i]);
    }
    var new_height = heightWithOffset(obj, offset);
    var total_lines;
    var line_offset;
    while (true) {
        total_lines = Math.ceil(new_height / line_height);
        line_offset = offset / (total_lines);
        var next_height = heightWithOffset(obj, offset + line_offset);
        if (next_height === new_height) break;
        new_height = next_height;
    }
    for (var i = 0; i < total_lines; i++) {
        var left_offset = line_offset * (i + 1);
        var right_offset = offset - left_offset + line_offset;
        if(invert){
            var hold = left_offset;
            left_offset = right_offset;
            right_offset = hold;
        }
        var div = document.createElement('div');
        div.className = 'rhombus_side';
        div.style.width = left_offset + 'px';
        div.style.height = line_height + 'px';
        div.style.float = 'left';
        div.style.clear = 'left';
        //div.style.backgroundColor = 'red';
        obj.insertBefore(div, obj.firstChild);
        div = document.createElement('div');
        div.className = 'rhombus_side';
        div.style.width = right_offset + 'px';
        div.style.height = line_height + 'px';
        div.style.float = 'right';
        div.style.clear = 'right';
        //div.style.backgroundColor = 'blue';
        obj.insertBefore(div, obj.firstChild);
    }
}

function heightWithOffset(obj, offset) {
    var old_padding_left = obj.style.paddingLeft;
    obj.style.paddingLeft = (offset + 1) + 'px';
    var new_height = obj.clientHeight;
    obj.style.paddingLeft = old_padding_left;
    return new_height;
}

function getLineHeight(element) {
    //Thank you : http://stackoverflow.com/a/4515470/482197
    var temp = document.createElement(element.nodeName);
    temp.setAttribute("style", "border:0;margin:0px;padding:0px;font-family:" + element.style.fontFamily + ";font-size:" + element.style.fontSize);
    temp.innerHTML = "test";
    temp = element.parentNode.appendChild(temp);
    var ret = temp.clientHeight;
    temp.parentNode.removeChild(temp);
    return ret;
}
//Below this is just my showing it with positive and negative offsets
var last_offset = 150;
function toggleRhombus(){
    last_offset *= -1;
    rhomboit(document.getElementById('rhombus'), last_offset);
    setTimeout(function(){toggleRhombus()},5000);
}
toggleRhombus();

<div id='rhombus' style='border:1px solid black;text-align:justify'>This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text This is text</div>

我不能说它的效率非常高，但它可以完成任务。
必须在px。
您可能希望在文档调整大小时再次调用它。

如果您想了解它是如何工作的，请取消注释两个样式线

Answer 2

您应该使用shape-inside, -webkit-shape-inside。
