網頁放大代碼
可以使用css3的scale縮放來實現
body{
transform: scale(0.5);
transform-origin: center top 0px;
}
⑵ html實現網頁上圖片放大功能代碼 就像新浪微博圖片放大一樣的那種，點一下放大再點一下就變成原來的狀態。

⑶ 怎麼樣把HTML代碼裡面的字體放大 放大的代碼是什麼
<html>
<head><title>字體大小 font size</title></head><body>
<p><font size="1">這段文字的字體大小值為1。</font></p>
<p><font size="2">這段文字的字體大小值為2。</font></p>
<p><font size="3">這段文字的字體大小值為3。</font></p>
<p><font size="4">這段文字的字體大小值為4。</font></p>
<p><font size="5">這段文字的字體大小值為5。</font></p>
<p><font size="6">這段文字的字體大小值為6。</font></p>
<p><font size="7">這段文字的字體大小值為7。</font></p></body>
</html> 數字代表大小...越大的數字代表字體更大.
(3)網頁放大代碼擴展閱讀
html5 和html的區別：
1.在文檔類型聲明上
html:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
html5:<!doctype html>
在文檔聲明上，html有很長的一段代碼，並且很難記住這段代碼，而html5卻不同，只有簡簡單單的聲明，這也方便人們的記憶。
2.在結構語義上
html:沒有體現結構語義化的標簽，通常都是這樣來命名的<div id="header"></div>，這樣表示網站的頭部。
html5:在語義上卻有很大的優勢。提供了一些新的標簽，比如:<header><article><footer>。
⑷ 設置 網頁 頁面大小的代碼是什麼
作個寬230高678的表格不就行了？
你要設置彈出窗口大小么？
SCRIPT LANGUAGE="javascript">
<!--
window.open ('page.html', 'newwindow', 'height=678, width=230, top=0, left=0, toolbar=no, menubar=no, scrollbars=no, sizable=no,location=no, status=no')
//寫成一行
-->
</SCRIPT>
⑸ 網頁代碼-放大鏡功能
你看你的代碼，把代碼中的圖片目錄替換成放大代碼中的圖片地址就可以了
不行的話郵件告訴我
⑹ 求能自動縮放網頁大小的代碼
取屏幕大小
screen.width
screen.height
根據屏幕大小縮放
if (window.screen.width=='600')
document.write ('<body style="zoom: 55%">');
else if (window.screen.width=='800')
document.write ('<body style="zoom: 75%">');
⑺ 控制一個網頁窗口的大小的代碼
直接這樣寫就行了:
<script language='javascript'>
window.open('4.html','','toolbar=no,menubar=no,location=no,status=no,width=500,height=500,left=100,top=100');
</script>
⑻ 如何實現HTML整體進行縮放 用css或javascript代碼都可以
你可以使用CSS zoom屬性
例如：
body {
zoom: 3;
-moz-transform: scale(3);
-moz-transform-origin: 0 0;
}
把整個body放大三倍,縮小同理,改成比1小的數字即可
⑼ 怎樣用代碼來縮放網頁啊....
Ctrl加滑鼠滾輪就可以縮放
代碼的話，你可以用css,然後用js響應時間進行style屬性替換
⑽ html文字大小代碼
一般標簽內都有style屬性，在style屬性裡面通過font-size就可以定義的<font style="font-size:12px">文字</font>
<span style="font-size:12px">文字</span>
另外版
<font size="30">文字</font>
<h1>文字</h1>
<h2>文字</h2>
<h3>文字</h3>
.....
還有好多權就不列舉了。
