如何将滑块按钮放置在页面的最左侧和右侧

Question

I recently placed a slider presentation in my site problem is that I want it to cover it from the far left to far right like a banner and also the image to resizes and fit the banner. 我最近在我的网站上放置了一个滑块演示文稿，问题是我希望它像横幅广告一样从最左边到最右边覆盖它，并且还希望图像能够调整横幅的大小和大小。 Here is a picture of the slider so far: 这是到目前为止的滑块图片：

Also wondering if the image and slider can also resize automatically with the size of the webpage. 还想知道图像和滑块是否也可以根据网页的大小自动调整大小。 So that it is mobile friendly and the website wouldn't mess up when it is not in fullscreen. 因此它是移动友好的，并且当它不是全屏显示时，网站也不会混乱。

Answer 1

Your slider is only 800px large and the prev and next determine their position from it so you need a larger container for them to get their position relative to it. 您的滑块只有800像素大，上一个和下一个从中确定它们的位置，因此您需要一个更大的容器来让他们获得相对于其的位置。

You can add a container with a width to 100% and move your buttons to it. 您可以添加宽度为100％的容器，然后将按钮移至该容器。

 .slideshow { width: 100%; position: relative; margin: auto; }

 <div class="slideshow"> <div class="slideshow-container"> .... </div> <a class="prev" onclick="plusSlides(-1)">&#10094;</a> <a class="next" onclick="plusSlides(1)">&#10095;</a> </div>
