1、准备好需要用到的图标。
2、新建html文档。
3、书写hmtl代码。<ul style="margin-top:50px;"> <li><a href="#">百度经验</a></li> <li><a href="index-html.html">百度经验</a></li> <li><a href="index-image.html">百度经验</a></li></ul><div id="content"> <div class="help-tip"> <p>百度经验</p> </div> <p>百度经验</p></div>
4、书写index颍骈城茇-html.html中body代码。<ul style="margin-top:50px;"><li><a href="index.html">百度经验</a></li><li><a href="index-html.html">百度经验</a></li><li><a href="index-image.html">百度经验</a></li></ul><div id="content"><div class="help-tip"> <p>百度经验<br> <br> <img src="images/balloon.jpg" width="300" /></p></div><p>百度经验</p></div>
5、书写index颍骈城茇-image.html中body代码。<ul style="margin-top:50px;"><li><a href="index.html">百度经验</a></li><li><a href="index-html.html">百度经验</a></li><li><a href="index-image.html">百度经验</a></li></ul><div id="content"><div class="help-tip"> <p>百度经验<b>百度经验</b> <a href="#">百度经验</a>百度经验<i><strike>百度经验</strike></i>!</p></div><p>百度经验</p></div>
6、书写css代码。* { margin: 0; padding: 0; }html { backgrou荏鱿胫协nd-color: #eaf0f2; }body { font: 14px/1.4 'Arial', 'Helvetica', sans-serif; color: #5b6469; }a, a:visited { outline: none; color: #389dc1; }a:hover { text-decoration: none; }section, footer, header, hgroup, aside { display: block; }p { margin-bottom: 20px; }p:last-child { margin-bottom: 0; }hgroup { text-align: center; padding: 60px 0 48px; font-family: 'PT Serif', 'Cambria', serif; }hgroup h1 { color: #828e93; font-size: 18px; font-weight: normal; }hgroup h2 { font-size: 48px; }ul { list-style: none; text-align: center; margin-bottom: 48px; }ul li { display: inline-block; margin: 0 8px; }ul li:hover { opacity: 0.9; }ul li a { color: #fff !important; text-decoration: none !important; font-size: 15px; font-weight: bold; display: inline-block; padding: 6px 14px; border-radius: 3px; box-shadow: 1px 1px 1px rgba(0,0,0,0.1); }ul li:nth-child(1) a { background-color: #6bb9e1; }ul li:nth-child(2) a { background-color: #ec7164; }ul li:nth-child(3) a { background-color: #6ad3c3; }#content { background-color: #FFF; border-radius: 4px; padding: 40px; margin: 0 auto; max-width: 600px; position: relative; margin: 0 auto 100px; }.help-tip { position: absolute; top: 18px; right: 18px; text-align: center; background-color: #BCDBEA; border-radius: 50%; width: 24px; height: 24px; font-size: 14px; line-height: 26px; cursor: default; }.help-tip:before { content: '?'; font-weight: bold; color: #fff; }.help-tip:hover p { display: block; transform-origin: 100% 0%; -webkit-animation: fadeIn 0.3s ease-in-out; animation: fadeIn 0.3s ease-in-out; }.help-tip p { display: none; text-align: left; background-color: #1E2021; padding: 20px; width: 300px; position: absolute; border-radius: 3px; box-shadow: 1px 1px 1px rgba(0, 0, 0, 0.2); right: -4px; color: #FFF; font-size: 13px; line-height: 1.4; }.help-tip p:before { position: absolute; content: ''; width: 0; height: 0; border: 6px solid transparent; border-bottom-color: #1E2021; right: 10px; top: -12px; }.help-tip p:after { width: 100%; height: 40px; content: ''; position: absolute; top: -40px; left: 0; }@-webkit-keyframes fadeIn { 0% {opacity:0;transform: scale(0.6);} 100% { opacity:100%; transform: scale(1);}}@keyframes fadeIn { 0% {opacity:0;} 100% {opacity:100%;}}footer { width: 770px; font: normal 16px Arial, Helvetica, sans-serif; padding: 15px 35px; position: fixed; bottom: 0; left: 50%; margin-left: -420px; background-color: #1f1f1f; background-image: linear-gradient(to bottom, #1f1f1f, #101010); border-radius: 2px 2px 0 0; box-shadow: 0 -1px 4px rgba(0,0,0,0.4); z-index: 1; }footer a.tz { font-weight: normal; font-size: 16px !important; text-decoration: none !important; display: block; margin-right: 300px; text-overflow: ellipsis; white-space: nowrap; color: #bfbfbf !important; z-index: 1; }footer a.tz:before { content: ''; background: url('../images/v2_footer_bg.png') no-repeat 0 -53px; width: 138px; height: 20px; display: inline-block; position: relative; bottom: -3px; }footer .close { position: absolute; cursor: pointer; width: 8px; height: 8px; background: url('../images/v2_footer_bg.png') no-repeat 0 0px; top: 10px; right: 10px; z-index: 3; }footer #tzine-actions { position: absolute; top: 8px; width: 500px; right: 50%; margin-right: -650px; text-align: right; z-index: 2; }footer #tzine-actions iframe { display: inline-block; height: 21px; width: 95px; position: relative; float: left; margin-top: 11px; }@media (max-width: 1024px) {#bsaHolder, footer { display: none; }}
7、代码整体结构。
8、html文档目录结构。
9、查看效果。
