現在很多網站都有註冊頁面和登入頁面,像是淘寶京東微信等這些都需要註冊登入的,那我們要如何用html5和css3寫出這些頁呢?現在就一步一步教大家如何用html和css3寫登入頁面。
login.html程式碼如下:
<form id="login"> <h1>Log In</h1> <fieldset id="inputs"> <input id="username" type="text" placeholder="Username" autofocus required> <input id="password" type="password" placeholder="Password" required> </fieldset> <fieldset id="actions"> <input type="submit" id="submit" value="Log in"> <a href="">Forgot your password?</a><a href="">Register</a> </fieldset> </form>
所用到的HTML 5的特性:
placeholder – 輸入框的簡短提示,當輸入框獲得輸入焦點時,此提示訊息會自動消失
required – 指定該輸入元素是否必須提供
autofocus – 指定輸入方塊是否在頁面載入完成自動取得輸入焦點
#type =”password” – 指定密碼輸入(非HTML5專有)
CSS
#在這裡我們用到了CSS3 的一些專有屬性,包括:
Box-shadow可以幫我們製作效果很好的邊框陰影
#login { box-shadow: 0 0 2px rgba(0, 0, 0, 0.2), 0 1px 1px rgba(0, 0, 0, .2), 0 3px 0 #fff, 0 4px 0 rgba(0, 0, 0, .2), 0 6px 0 #fff, 0 7px 0 rgba(0, 0, 0, .2); } Stitch effect (缝效果) #login { position: absolute; z-index: 0; } #login:before { content: ''; position: absolute; z-index: -1; border: 1px dashed #ccc; top: 5px; bottom: 5px; left: 5px; right: 5px; -moz-box-shadow: 0 0 0 1px #fff; -webkit-box-shadow: 0 0 0 1px #fff; box-shadow: 0 0 0 1px #fff; }
Subtle gradient lines (微妙的漸層線)
h1 { text-shadow: 0 1px 0 rgba(255, 255, 255, .7), 0px 2px 0 rgba(0, 0, 0, .5); text-transform: uppercase; text-align: center; color: #666; margin: 0 0 30px 0; letter-spacing: 4px; font: normal 26px/1 Verdana, Helvetica; position: relative; } h1:after, h1:before { background-color: #777; content: ""; height: 1px; position: absolute; top: 15px; width: 120px; } h1:after { background-image: -webkit-gradient(linear, left top, right top, from(#777), to(#fff)); background-image: -webkit-linear-gradient(left, #777, #fff); background-image: -moz-linear-gradient(left, #777, #fff); background-image: -ms-linear-gradient(left, #777, #fff); background-image: -o-linear-gradient(left, #777, #fff); background-image: linear-gradient(left, #777, #fff); right: 0; } h1:before { background-image: -webkit-gradient(linear, right top, left top, from(#777), to(#fff)); background-image: -webkit-linear-gradient(right, #777, #fff); background-image: -moz-linear-gradient(right, #777, #fff); background-image: -ms-linear-gradient(right, #777, #fff); background-image: -o-linear-gradient(right, #777, #fff); background-image: linear-gradient(right, #777, #fff); left: 0; }
