[英]HTML5 Fitting To Screen Resolution
我一直在寻找解决方案，运气很小。 我不太擅长HTML或CSS。 我了解基本知识，但是我需要用HTML 5编写的内容。因此，我将非常感谢您的协助。
我使用这个网站来了解我要在这里做什么。
它应该是可以在Android，iPhone和iPad上显示的HTML5应用。 它确实没有很多功能。 主要是能够像链接显示一样滑动来翻转页面的功能。 我的问题是我无法获取图像，并且无论从哪个屏幕上来看，图像都无法容纳。 似乎很难将其编码为适合iPhone大小，但是在iPad上显示时，它只占据屏幕的一小部分。 我将在下面发布他的代码，因此您不必去那里查看它。

我添加了imageFit，因为图像没有缩放到屏幕尺寸，这是我的尝试。 看来无论如何它都适合最大宽度。 如果有更好的方法或者您知道解决方法，我将非常感谢您的帮助。 谢谢
尝试更改以下代码：
//for iPhone, the width and height
swipey.preferredWidth = 320;
swipey.preferredHeight = 416; //510 for android
至：
//Auto-detect resolution via javascript:
swipey.preferredWidth = screen.width;
swipey.preferredHeight = screen.height;
这将使用javascript自动检测屏幕分辨率。
然后，脚本会将li宽度乘以li元素的数量，以调整slideContainer ul以适合内容：
//setting the width to our <ul> element which holds all the <li> elements
swipey.slideContainer.style.width = swipey.slides.length * swipey.preferredWidth + "px";
swipey.slideContainer.style.height = swipey.preferredHeight + "px";
//calculating the max distance of travel for Slide Container i.e <ul> element
swipey.maxDistance = swipey.slides.length * swipey.preferredWidth;
如果上述方法无效，请尝试删除#imgFit样式，看看它是否可以解决滚动问题。 问题。 它可能会干扰某些事情。
此外，通过使用内联样式将图像的宽度和高度设置为100％，当以不同的分辨率加载时，它们的外观将成比例。 如果要使图像保持特定比例，可以尝试将宽度设置为100％，然后浏览器应正确缩放。
HTML5 Javascript移动应用程序不适用于较小分辨率的平板电脑
