Preface

This article mainly summarizes some of the solutions to problems encountered when making daily web pages and shares them with you. It’s for everyone’s reference and study. I won’t say much below. Friends who are interested can take a look at the detailed introduction:

The summary is as follows:

1. Box-sizing: Allows you 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 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 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" />

8.Multiple Use ellipsis to indicate the text

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。*/

9. How to remove the blue background color when clicking on the text on the css page

-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;

10. You can use this attribute when it is difficult to adjust the vertical position of the icon

vertical-align: 30%;
vertical-align: middle;

11. How to center a p up, down, left, and right in the page

p{
    width:400px;
    height:300px;
    position:absolute;
    top:50%;
    left:50%;
    margin:-150px 0 0 -200px;
}

12.js

// 在js中写的返回键
onclick = 'history.go(-1)';

// 强制刷新页面
window.location.reload(true);

13. Line break, no line break, word spacing
