溢出滚动不适用于班级孩子

标签： html css overflow

我尝试仅为文本添加overflow:scroll，文本被类element-text包围，但不起作用，什么也没发生。我在父类（element）中具有相对位置，而在子类（element-text）中具有绝对位置。这是我的代码codepen。

HTML：

        <div class="person-box">
            <a href="{{ url('#') }}"><div class="person-photo-autor"></div></a>

答案 0 :(得分：1)

我将所有容器调整为absolute，并从top:0移至bottom:0，从left:0移至right:0，以便它们都具有确切的尺寸/尺寸。

.element-text overflow-y设置为auto，因此在需要时显示scrollBar。

//Slider
class Slider {
  constructor(elemSelector, opts) {

    const defaultOptions = {
      pauseTime: 0,
      nextText: "następny slide",
      prevText: "poprzedni slide",
      generateDots: true,
      generatePrevNext: true
    };

    this.options = Object.assign({}, defaultOptions, opts);

    this.currentSlide = 0;
    this.sliderSelector = elemSelector;
    this.elem = null;
    this.slider = null;
    this.slides = null;
    this.prev = null;
    this.next = null;
    this.dots = [];

    this.generateSlider();
    this.changeSlide(this.currentSlide);
  }

  changeSlide(index) {

    //slide
    [].forEach.call(this.slides, function(slide) {
      slide.classList.remove('element-date-animate');
      slide.classList.remove('slider-slide-active');
      slide.setAttribute('arian-hidden', true);
    });

    this.slides[index].classList.add('element-date-animate');
    this.slides[index].classList.add('slider-slide-active');
    this.slides[index].setAttribute('aria-hidden', false);

    //dots
    if (this.options.generateDots) {

      this.dots.forEach(el => {
        el.classList.remove('slider-dots-element-active');
      });
      this.dots[index].classList.add('slider-dots-element-active');

    }

    this.currentSlide = index;


    if (typeof this.options.pauseTime === 'number' && this.options.pauseTime !== 0) {

      clearInterval(this.time);
      this.time = setTimeout(function() {

      btn.addEventListener("click", () => {
        this.changeSlide(i);
      });

      li.appendChild(btn);
      ulDots.appendChild(li);

      this.dots.push(li);


    }

    this.slider.appendChild(ulDots);
  }

    overflow: scroll;
    max-width: 500px;
    max-height: 200px;
