When we programmers make web pages, of course we hope to make a very beautiful web page, so in this article we will teach you several very useful tips for making web pages.
1. box-sizing: allows to define specific elements that match a certain area in a specific way.
content-box: Add padding and borders to the box in addition to the specified width and height.
border-box: (textarea and select default value) Add inner margins and borders to the box within the specified width and height of the box.
/*看个人习惯而用,但一般标签默认属性是content-box,除textarea,select*/ box-sizing: content-box; -moz-box-sizing: content-box; -webkit-box-sizing: content-box;
2. Beautify the input box
/*在IE10+浏览器中, 使用css即可隐藏input文本输入框右侧的叉号*/ input[type=text]::-ms-clear,::-ms-reveal{display:none;} input::-ms-clear,::-ms-reveal{display:none;} input{ /*去除点击出现轮廓颜色*/ outline: none; /*padding已在重置样式中去除,如果没有去除,记得有padding哦*/ }
3. Beautify the textarea text area
textarea{ /*别忘了文本域的box-sizing属性值是border-box;所有的边框和padding都是在你固定的宽高的基础上绘制*/ /*去除点击出现轮廓颜色*/ outline: none; /*如果有需要,去掉右下角的可拉伸变大小的图标和功能*/ resize: none; /*padding已在重置样式中去除,如果没有去除,记得有padding哦*/ }
4. Change the font color size of the placeholder
input::-webkit-input-placeholder { /* WebKit browsers */ font-size:14px; color: #333; } input:-moz-placeholder { /* Mozilla Firefox 4 to 18 */ font-size:14px; color: #333; } input::-moz-placeholder { /* Mozilla Firefox 19+ */ font-size:14px; color: #333; } input:-ms-input-placeholder { /* Internet Explorer 10+ */ font-size:14px; color: #333; }
5. Beautify the select
/*清除ie的默认选择框样式清除,隐藏下拉箭头*/ select::-ms-expand { display: none; } select { /*Chrome和Firefox里面的边框是不一样的,所以复写了一下*/ border: solid 1px #333; /*将默认的select选择框样式清除*/ appearance:none; -moz-appearance:none; -webkit-appearance:none; /*在选择框的最右侧中间显示小箭头图片*/ background: url("小箭头图片路径") no-repeat right center transparent; /*为下拉小箭头留出一点位置,避免被文字覆盖*/ padding-right: 14px; /*去除点击出现轮廓颜色*/ outline: none; }
6. Beautify the button button
button{ /*本身有2px的边框,一般的button都不需要边框*/ border: none; /*本身有的背景色,可以用其他颜色取代*/ background: #333; /*padding已在重置样式中去除,如果没有去除,记得有padding哦*/ }
7. Beautify the radio button, multi-select box or upload file button
/*因为用input[type="radio"]和input[type="cheakbox"]都不能直接改变它们的样式,这个时候要用到label标签关联,然后隐藏input标签,直接给label标签样式就好了。选中label就是选中了此标签*/ <label for="sex">男</label> <input type="radio" id="sex" value="男" />
white-space: nowrap; /* 强制不换行 */ overflow:hidden; / *内容超出宽度时隐藏超出部分的内容 */ text-overflow:ellipsis;/* 当对象内文本溢出时显示省略标记(...) ,需与overflow:hidden;一起使用。*/
-moz-user-select: none; /* 火狐 */ -webkit-user-select: none; /* webkit浏览器 */ -ms-user-select: none; /* IE10 */ -khtml-user-select: none; /* 早期浏览器 */ user-select: none;
vertical-align: 30%; vertical-align: middle;
div{ width:400px; height:300px; position:absolute; top:50%; left:50%; margin:-150px 0 0 -200px; }
// 在js中写的返回键 onclick = 'history.go(-1)'; // 强制刷新页面 window.location.reload(true);
