程序員浪漫起來沒文科生什么事：HTML制作表白愛心-無需編程基礎(chǔ)

說程序員是大大的直男，但是一旦程序員浪漫起來，他們會用他們狂拽酷炫吊的技能展現(xiàn)自己的羅曼蒂克實(shí)力，那時候就真的沒文科男什么事啦！下面我就跟大家分享如何用簡單的html制作一個網(wǎng)頁版的愛心表白，不管你是不是程序員都能用，手機(jī)就可展示。

先來看下效果：

后面會提供給大家源代碼，在這里先交大家怎么去根據(jù)自己的實(shí)際情況去改這個文件。

復(fù)制源代碼

首先大家將我后面的源代碼復(fù)制下來并且粘貼進(jìn)一個txt文件就可以。

jquery.js下載

不要看到下載就害怕，這個大家只要搜索jquery就能下載了，下載完是一個jquery.js文件，將文件改名為jquery.txt，雙擊打開將內(nèi)容復(fù)制到下圖所示位置。（如果有人不會下，可以私信我索要）

更改表白信息

大家根據(jù)自己的實(shí)際請款更改頁面的一些信息，比如姓名，日期、或者是表白內(nèi)容都可以

源碼

最后奉上源碼，這里是沒有jquery.js的，已經(jīng)預(yù)留空，需要大家復(fù)制粘貼進(jìn)來就行了，最后將txt文件的后綴改為.html就可以了，不管是電腦還是手機(jī)都能用哦。

言：每當(dāng)過節(jié)的時候，女朋友就抱怨我總是忘記給她買花，說程序不懂浪漫，這不我準(zhǔn)備了幾款愛心動畫特效，打算當(dāng)面向她表達(dá)一下。

第一款：html5通過canvas實(shí)現(xiàn)浪漫告白愛心動畫特效

寓意：告白無須多么華麗的語言，一顆顆小的愛心匯聚成一顆真心，讓你的另一半感受到濃濃的愛意。

代碼難度系數(shù)★★★

代碼有image、js和html，所以不好貼出來，有需要的朋友直接問我要吧。

總結(jié)：程序員的工作本身就很枯燥，特定找了幾個好看的特效拿出來和大家分享，希望大家能夠快樂每一天，上述代碼親測可用，歡迎點(diǎn)贊收藏。

《完》

大家如果喜歡的話麻煩點(diǎn)贊、關(guān)注、轉(zhuǎn)發(fā)，謝謝大家。

嘍，首先和大家說聲抱歉，停更了這么久，主要是期間因?yàn)楣ぷ髡{(diào)動的關(guān)系，工作變忙了，沒有時間來更新了，今天趁著領(lǐng)導(dǎo)不在，偷偷來更新一下吧~

首先我的分享方式可能和別人的不同，別人可能是從最開始的一步一步開始教起，我不是，我是先把效果展示給大家，讓大家先看看這個東西，然后我再開始講，有看不下去的現(xiàn)在就可以吧網(wǎng)頁關(guān)了，免得看完又來噴我，我不是什么大神，噴我有什么用？我看的心里還不舒服，是吧，為了營造良好的網(wǎng)絡(luò)環(huán)境，別噴啊~

接下來進(jìn)入主題：

大家可能都看過下面的這個網(wǎng)頁截圖

這個是一個類似于計(jì)時器的這么一個情侶間的網(wǎng)頁，今天我的目的就是把大家都教會了(不會的我下面會放源碼)，然后回家有興趣的可以做好展示給自己的另一半看看~

我也放個網(wǎng)址吧，讓你們可以看看實(shí)際效果是什么樣的

http://1.giggle.applinzi.com/shouye1.html

就是這個樣子，雖然可能過氣了吧，但是我相信你的另一半看完還是會很感動的

那么接下來，我要放html的源碼了:然后我會開始講解:

上面這個就是html的源碼，當(dāng)然還有css和js的源碼我還沒有給到大家，主要是大家目前還沒有對html有個了解，再去學(xué)css和js就會有點(diǎn)懵逼的樣子了

那我從第一行開始講起吧，

第一行是告訴瀏覽器，我這個是HTML5，所以你要用h5的格式去解析。這個不是很重要，反正每個頁面上都有的。

第二行之前講過，我就不再敘述了，是html網(wǎng)頁的開頭標(biāo)簽，相當(dāng)于就是告訴html，我要開始寫代碼啦

第三行之前也講過，是html中的頭文件開頭標(biāo)簽

第四行meta是告訴瀏覽器接受一個html文檔

等等，領(lǐng)導(dǎo)回來了……，我明天再說了
