在 iPhone/iPad 上查看时网站上的 div 之间存在空格/间隙

问题描述 投票:0回答:3

在 iPhone 和 iPad 上查看时,我的网站无法正确显示。该网站(甚至还没有接近完成)是 www.lzkconcepts.com。

在我尝试过的每个桌面浏览器(safari、chrome、firefox、IE)上查看时,该网站都能正确显示,但是,在 iPhone/iPad 上,“内容”div 与页眉和页脚之间存在微小间隙/空间。我在页眉、内容和页脚 div 中使用背景图像来创建页面的轮廓。除了 div 之间的间隙之外,内容背景图像有时会稍微“缩小”,因此它不会与屏幕右侧的页眉和页脚对齐。如果我放大,一切都完美排列。这是从 iPhone 上截取的屏幕截图...

仔细观察蓝色导航栏下方的右侧。

这是CSS(我知道它很粗糙,我只是在学习)

Remember that what you do here will cascade to the .nav list unless you write a more specific selector. */
 padding: 0;
 margin: 0;
}
h1, h2, h3, h4, h5, h6, p {
 margin-top: 0;  /* removing the top margin gets around an issue where margins can escape from their containing div. The remaining bottom margin will hold it away from any elements that follow. */
 padding-right: 15px;
 padding-left: 15px; /* adding the padding to the sides of the elements within the divs, instead of the divs themselves, gets rid of any box model math. A nested div with side padding can also be used as an alternate method. */

}

/* ~~ This is the layout information. ~~ 

1) Padding is only placed on the top and/or bottom of the div. The elements within this div have padding on their sides. This saves you from any "box model math". Keep in mind, if you add any side padding or border to the div itself, it will be added to the width you define to create the *total* width. You may also choose to remove the padding on the element in the div and place a second div within it with no width and the padding necessary for your design.

有人知道为什么 iPhone 和 iPad 会这样渲染页面吗?

在 iPad 上,当以低于 100% 的比例查看网站时,有时会出现一些伪影。其中一个特别明显:div 之间有 1 像素的线,就像在您的网站上的菜单下一样。

我找到的解决方案是在div之间添加“margin:-1px”。 Div 背景重叠 1 像素,如果进行相应的切片,则对于经典浏览器来说是不可见的,并纠正了 iPad 上的问题。

用途:

meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;"

当网站显示在平板电脑或其他设备上时。这应该消除您看到的像素差异。如今,网站的设计应在语义上可扩展,以实现最大程度的跨设备访问。

对于我来说,如果绝对需要解决问题,我通常会构建一个 php 设备检测器。

.expand {
    transform-origin: 0 100%;
    transform: scaleY(1.01);
}

<div class="expand">Content for div1</div>
<div class="expand">Content for div2</div>
<div class="expand">Content for div3</div>

此 CSS 代码使每个 div 垂直拉伸 1%,与相邻的 div 重叠,从而有可能消除您所看到的可见伪影。

变换原点:0 100%;声明将变换的原点更改为元素的左下角(0% X 轴,100% Y 轴)。因此,当应用scaleY转换时,您的元素从底部扩展,有效地重叠下面的div。

在我看来,这是一种更实用、更安全的处理问题的方法,然后使用负边距,除非您每次在下一节中增加这些边距,否则我不知道它会如何工作。
