Jquery CSS-页面上的随机行

我正在使用一个用于进度条的库，这是一个简单的jQuery插件，允许我显示工作流中的步骤以及它们是否完成

我也在使用引导

本质上，使用这个插件会在页面上造成一条灰线，然而，当使用Chromes inspector时，我根本找不到是什么导致了灰线

更重要的是，十六进制调色板上的行是#cfcfcf，我已经搜索了这个十六进制代码的整个解决方案，但找不到任何与该颜色相关的内容

这是这条线的截图：（对不起，它被放大了，我想弄清楚这条线在哪里）

我的HTML：

<div class="progress-bar-wrapper"></div>

JS：

//A wrapper to encapsulate all the code
(function (window) {
  function initProgressBar() {
var ProgressBar = {};
ProgressBar.singleStepAnimation = 1000; //default value
// this delay is required as browser will need some time in rendering and then processing css animations.
var renderingWaitDelay = 200;

// A utility function to create an element
var createElement = function (type, className, style, text) {
  var elem = document.createElement(type);
  elem.className = className;
  for (var prop in style) {
    elem.style[prop] = style[prop];
  }
  elem.innerHTML = text;
  return elem;
};

var createStatusBar = function(stages, stageWidth, currentStageIndex) {
  var statusBar = createElement('div', 'status-bar', {width: 100 - stageWidth + '%'}, '');
  var currentStatus = createElement('div', 'current-status', {}, '');

  setTimeout(function() {
    currentStatus.style.width = (100 * currentStageIndex)/(stages.length - 1)+'%';
    currentStatus.style.transition = 'width '+(currentStageIndex * ProgressBar.singleStepAnimation)+'ms linear';
  }, renderingWaitDelay);

  statusBar.appendChild(currentStatus);
  return statusBar;
};

var createCheckPoints = function(stages, stageWidth, currentStageIndex) {
  var ul = createElement('ul', 'progress-bar', { }, '');
  var animationDelay = renderingWaitDelay;
  for (var index = 0; index < stages.length; index++) {
    var li = createElement('li', 'section', {width: stageWidth + '%'}, stages[index]);
    if(currentStageIndex >= index) {
      setTimeout(function(li, currentStageIndex, index) {
        li.className+= (currentStageIndex > index)?' visited': ' visited current';
      }, animationDelay, li, currentStageIndex, index);
      animationDelay+= ProgressBar.singleStepAnimation;
    }
    ul.appendChild(li);
  }
  return ul;
};

var createHTML = function (wrapper, stages, currentStage) {
  var stageWidth = 100 / stages.length;
  var currentStageIndex = stages.indexOf(currentStage);

  //create status bar
  var statusBar = createStatusBar(stages, stageWidth, currentStageIndex);
  wrapper.appendChild(statusBar);

  //create checkpoints
  var checkpoints = createCheckPoints(stages, stageWidth, currentStageIndex);
  wrapper.appendChild(checkpoints);

  return wrapper;
};

var validateParameters = function(stages, currentStage, container) {
  if(!(typeof stages === 'object' && stages.length && typeof stages[0] === 'string')) {
    console.error('Expecting Array of strings for "stages" parameter.');
    return false;
  }
  if(typeof currentStage !== 'string') {
    console.error('Expecting string for "current stage" parameter.');
    return false;
  }
  if(typeof container !== 'string' && typeof container !== 'undefined') {
    console.error('Expecting string for "container" parameter.');
    return false;
  }
  return true;
};

//exposing this function to user;
ProgressBar.init = function (stages, currentStage, container) {
  if(validateParameters(stages, currentStage, container)) {
    var wrapper = document.getElementsByClassName(container);
    if(wrapper.length > 0) {
      wrapper = wrapper[0];
    } else {
      wrapper = createElement('div', 'progressbar-wrapper', { }, '');
      document.body.appendChild(wrapper);
    }
    createHTML(wrapper, stages, currentStage);
  }
};
return ProgressBar;
  }

  if (typeof ProgressBar === 'undefined') {
window.ProgressBar = initProgressBar();
  } else {
console.log('Progress bar loaded');
  }

})(window);

我有一个演示，我没有使用引导，也没有下划线/边框等

我只是不知道该从哪里找到这条讨厌的线的来源。

当我陷入类似的问题时，它是一些：后或：前样式，带有不同div块的边框

尝试改变各种元素的背景。这会有帮助

最终的方法是：逐个删除Chromes inspector中的子元素，直到线条消失。

是“Received”下的灰色线条吗？是的-整个东西下的全宽线条。相当肯定的是，它与UL相反：

//A wrapper to encapsulate all the code
(function (window) {
  function initProgressBar() {
var ProgressBar = {};
ProgressBar.singleStepAnimation = 1000; //default value
// this delay is required as browser will need some time in rendering and then processing css animations.
var renderingWaitDelay = 200;

// A utility function to create an element
var createElement = function (type, className, style, text) {
  var elem = document.createElement(type);
  elem.className = className;
  for (var prop in style) {
    elem.style[prop] = style[prop];
  }
  elem.innerHTML = text;
  return elem;
};

var createStatusBar = function(stages, stageWidth, currentStageIndex) {
  var statusBar = createElement('div', 'status-bar', {width: 100 - stageWidth + '%'}, '');
  var currentStatus = createElement('div', 'current-status', {}, '');

  setTimeout(function() {
    currentStatus.style.width = (100 * currentStageIndex)/(stages.length - 1)+'%';
    currentStatus.style.transition = 'width '+(currentStageIndex * ProgressBar.singleStepAnimation)+'ms linear';

  statusBar.appendChild(currentStatus);

ProgressBar.singleStepAnimation = 600;

    'Step 3',
    'Step 4',
    'Step 5'
  ],
  '@progressBar',
