我在理解視口概念。我用下面的測試HTML:理解視口

<html> 
<head> 
<meta name="viewport" content="width=1500, initial-scale=1"> 
<title>Test page to understand view port</title> 
</head> 
<body> 
<div>1. Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</div> 
<div>2. Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32. </div>

因爲我設置視寬度爲1500,我告訴瀏覽器的頁面是專爲1500px寬屏幕。所以我希望我的Chrome可以將頁面縮放到我的HTC One的小屏幕,並且我期望字體很小。但是,這就是我得到:

有人能解釋我這樣的結果?

它出現的原因是因爲您告訴視口渲染內容,就好像屏幕寬度爲1500像素寬。顯然這個設備沒有1500的寬度,所以內容看起來非常大。

這是一個非常不錯的網頁,將概括所有與視做:https://developer.mozilla.org/en/docs/Mozilla/Mobile/Viewport_meta_tag

嘗試設置寬度是這樣的:<meta name="viewport" content="width=device-width">
