HTML5是一種用于構(gòu)建網(wǎng)頁的開放源代碼語言，它的出現(xiàn)使得網(wǎng)頁設計變得更加簡單、靈活。
下面是一個HTML5的簡單實例源代碼：` 標簽定義文檔的標題，顯示在瀏覽器的標簽頁上；
- `<body>` 標簽包含文檔的主要內(nèi)容，如文本、圖像、表格等；
- `<p>` 標簽定義一個段落。
這個簡單的HTML文檔會在瀏覽器中顯示一個標題為“Hello World!”的頁面，并包含一個段落，其中包含文本“Hello World!”。
HTML5中的標簽有很多種，每種標簽都有自己的用途。開發(fā)人員可以根據(jù)需要選擇不同的標簽和屬性來構(gòu)建網(wǎng)頁。</div><div id="c2og2q0" class="share"></div><div id="wskkcek" class="Prev_Next"><div id="ekse00e" class="box">上一篇<a href="http://www.lofty888.cn/post/1116231.html">jquery imagescroller</a></div><div id="ggyuas2" class="box">下一篇<a href="http://www.lofty888.cn/post/1083219.html">html5 答題模板 代碼</a></div></div></div><div id="wowcuac" class="related related-list"><h5>相關文章</h5><ul><li><a href="http://www.lofty888.cn/post/1469806.html">html基礎教程都有哪些標題，詳細說明</a><span>08-04</span></li><li><a href="http://www.lofty888.cn/post/1299849.html">html畫八卦動態(tài)代碼</a><span>06-30</span></li><li><a href="http://www.lofty888.cn/post/1298508.html">html電子郵件鏈接怎么設置</a><span>06-30</span></li><li><a href="http://www.lofty888.cn/post/1298599.html">html電影代碼教程</a><span>06-30</span></li><li><a href="http://www.lofty888.cn/post/1298398.html">html電子商城源代碼</a><span>06-30</span></li><li><a href="http://www.lofty888.cn/post/1298609.html">html電子相冊代碼送女友</a><span>06-30</span></li><li><a href="http://www.lofty888.cn/post/1298930.html">html電影網(wǎng)頁源代碼</a><span>06-30</span></li><li><a href="http://www.lofty888.cn/post/1297409.html">html田字格布局怎么設置</a><span>06-30</span></li><li><a href="http://www.lofty888.cn/post/1297503.html">html電商網(wǎng)站開源代碼</a><span>06-30</span></li><li><a href="http://www.lofty888.cn/post/1298538.html">html電子郵箱鏈接代碼</a><span>06-30</span></li><li><a href="http://www.lofty888.cn/post/1298495.html">html電子郵件鏈接代碼</a><span>06-30</span></li><li><a href="http://www.lofty888.cn/post/1299073.html">html電影院訂票代碼</a><span>06-30</span></li><li><a href="http://www.lofty888.cn/post/1297960.html">html電子書翻頁效果代碼</a><span>06-30</span></li><li><a href="http://www.lofty888.cn/post/1298838.html">html電影介紹網(wǎng)站代碼</a><span>06-30</span></li><li><a href="http://www.lofty888.cn/post/1299411.html">html電腦特效代碼</a><span>06-30</span></li><li><a href="http://www.lofty888.cn/post/1083212.html">html5 移動端源代碼</a><span>05-22</span></li><li><a href="http://www.lofty888.cn/post/1087690.html">html5字幕滾動效果代碼</a><span>05-15</span></li><li><a href="http://www.lofty888.cn/post/717706.html">html怎么使用？</a><span>04-24</span></li><li><a href="http://www.lofty888.cn/post/719165.html">HTML教程讓你的圖片輕松向下移動</a><span>04-24</span></li><li><a href="http://www.lofty888.cn/post/1093530.html">html5設置字體為黑體</a><span>05-14</span></li><li><a href="http://www.lofty888.cn/post/1070331.html">html div設置寬高</a><span>05-25</span></li><li><a href="http://www.lofty888.cn/post/725094.html">如何學習HTML并進行方法模仿</a><span>04-20</span></li><li><a href="http://www.lofty888.cn/post/1194041.html">html怎么讓多張圖片設置</a><span>06-06</span></li><li><a href="http://www.lofty888.cn/post/714813.html">HTML代碼的顏色代碼（詳解HTML中的顏色代碼）</a><span>04-23</span></li><li><a href="http://www.lofty888.cn/post/1081984.html">html5 網(wǎng)站 源代碼</a><span>05-14</span></li><li><a href="http://www.lofty888.cn/post/1084363.html">html5中purple的代碼</a><span>05-20</span></li><li><a href="http://www.lofty888.cn/post/721181.html">HTML設置input樣式（讓你的input標簽更加美觀）</a><span>04-21</span></li><li><a href="http://www.lofty888.cn/post/721620.html">html設置漸進色（實現(xiàn)網(wǎng)頁漸變色的方法）</a><span>04-20</span></li><li><a href="http://www.lofty888.cn/post/727420.html">用html+echarts，讓你的運營數(shù)據(jù)分析更高效</a><span>04-20</span></li><li><a href="http://www.lofty888.cn/post/1069301.html">dw中關閉窗口代碼html</a><span>05-24</span></li></ul></div></div></div></div><div class="eq2qyym" id="footer"><div id="0uuesmq" class="copyright"><div id="qecm020" class="container"><p>老白網(wǎng)絡 (http://www.lofty888.cn/) 前端 后端 zblog主題.<a href="http://www.lofty888.cn/sitemap/post.html">網(wǎng)站地圖</a><a href="http://www.lofty888.cn/sitemap/post.xml">xml</a></p><span>Powered By Z-BlogPHP</span></div></div></div><div id="cccm0w2" class="bottom_tools"><a id="scrollUp" href="javascript:;" title="返回頂部"><i class="fa fa-angle-up"></i></a></div><script type="text/javascript" src="http://cdn.staticfile.org/jquery/2.2.4/jquery.min.js"></script><script src="http://cdn.yzktw.com.cn/zb_users/theme/ydproduct/script/ads.js" type="text/javascript"></script><script src="http://cdn.yzktw.com.cn/zb_users/theme/ydproduct/script/common.min.js" type="text/javascript"></script><script src="http://cdn.staticfile.org/prettify/r298/prettify.min.js" type="text/javascript"></script><script>jQuery(window).load(function(){jQuery("pre").addClass("prettyprint");prettyPrint();});</script><div class="geygw0g" id="ly_cache" data-id="1083222"></div>
