 box-sizing: border-box;
 white-space: nowrap; 
 z-index: 100;
 background: white;

js code:

//index.js
//获取应用实例
var app = getApp();
var mtabW;
Page({
 data: {
 tabs:["综合与绘画","艺术喷漆","泥塑","纸面绘画","布面绘画","中国油画","水墨画"],
 activeIndex:0,
 slideOffset:0,
 tabW:0
 },
 //事件处理函数
 onLoad: function () {
  var that = this;
  wx.getSystemInfo({
   success: function (res) {
    mtabW = res.windowWidth / 4; //设置tab的宽度
    that.setData({
     tabW:mtabW
    })
   }
  });

 },
 bindViewTap: function() {
 wx.navigateTo({
  url: '../logs/logs'
 })
 },
 tabClick:function(e){
  var that = this;
  var idIndex = e.currentTarget.id;
  var offsetW = e.currentTarget.offsetLeft; //2种方法获取距离文档左边有多少距离
  this.setData({
  activeIndex:idIndex,
  slideOffset:offsetW
  });
 },
 bindChange:function(e){
  var current = e.detail.current;
  if((current+1)%4 == 0){

  }
  var offsetW = current * mtabW; //2种方法获取距离文档左边有多少距离
  this.setData({
   activeIndex:current,
   slideOffset:offsetW
  });

 }

})
