    如何去除ie的select下拉框箭头图标

    <style>
            select {
                /*将默认的select选择框样式清除*/
                appearance: none;
                -moz-appearance: none;
                -webkit-appearance: none;
                background: url("/assets/img/caret.png") no-repeat scroll right center transparent;
            }
    
            /*清除ie的默认选择框样式清除,隐藏下拉箭头*/
            select::-ms-expand {
                display: none;
            }
        </style>

     二、有间隙,原来是input大小不包括边框,当selet和input同事存在同事有设置边框,如select的高度设置30px,则input[type='text'](注:input[type='submit']设置30px也没影响,不会有缝隙,自测)高度设置28px就可以

    解决后:

    select的css width样式,包含边框和内边距,即:真实的width=CSS width。

    而input的css width样式,则不包含边框和内间距,真实的width=CSS width border padding。

    代码:

    <div class="public_form_right">
                    <div class="public_fr_list">
                        <select name="sheng" class="public_che_sel fl">
                            <option value="京"></option>
                        </select>
                        <select name="frist" class="public_che_sel fl">
                            <option value="A">A</option>
                        </select>
                        <input type="text" class="public_che_input fl">
                        <input type="submit" class="btn fl" value="车牌测吉凶">
                    </div>
                </div>

    样式:

    .public_form_right{ overflow: hidden; background-color: #fff; padding-bottom: 10px;}
    .public_form_title{ height: 37px;line-height: 37px; color: #774889; font-size: 20px; border-bottom: 1px solid #eae8e9; padding: 0 10px; display: block;}
    .public_fr_list{ overflow: hidden; margin:10px 10px 0;border: 1px solid #d1d1d1; border-right:0;}
    .public_fr_list select{ float: left; height: 30px; line-height: 30px;}
    .public_fr_list input[type='text']{ padding-left: 5px; float: left; height: 28px; line-height: 28px;}
    .public_fr_list .btn{ width: 80px;text-align: center; background-color: #f0f0f0; color: #575757; height: 30px; line-height: 30px; font-family: "Microsoft Yahei";font-size: 14px;border-right: 1px solid #d1d1d1; cursor: pointer; box-sizing: border-box}
    .public_fr_list .btn:hover{ color: #fff; background-color: #b0afaf;}
    /* 车牌测吉凶 */
    .public_che_sel{ width: 54px; border:0; border-right: 1px solid #d1d1d1;}
    .public_che_input{ width: 85px; border:0; border-right: 1px solid #d1d1d1;}

    三、注意:按钮同个命名,a标签宽度设置80不会有缝隙,用input[type="submit"]同样宽度设置80px,但是会有1像素的缝隙,加个样式就不会了,宽度设置为81px;box-sizing: border-box;如图:

    样式设置:

    box-sizing: border-box;

    .public_form_right{ overflow: hidden; background-color: #fff; padding-bottom: 10px;}
    .public_form_title{ height: 37px;line-height: 37px; color: #774889; font-size: 20px; border-bottom: 1px solid #eae8e9; padding: 0 10px; display: block;}
    .public_fr_list{ overflow: hidden; margin:10px 10px 0;border: 1px solid #d1d1d1; border-right:0;}
    .public_fr_list select{ float: left; height: 30px; line-height: 30px;}
    .public_fr_list input[type='text']{ padding-left: 5px; float: left; height: 28px; line-height: 28px;}
    .public_fr_list .btn{ width: 80px;text-align: center; background-color: #f0f0f0; color: #575757; height: 30px; line-height: 30px; font-family: "Microsoft Yahei";font-size: 14px;border-right: 1px solid #d1d1d1; cursor: pointer; box-sizing: border-box}
    .public_fr_list .btn:hover{ color: #fff; background-color: #b0afaf;}
    /* 车牌测吉凶 */
    .public_che_sel{ width: 54px; border:0; border-right: 1px solid #d1d1d1;}
    .public_che_input{ width: 85px; border:0; border-right: 1px solid #d1d1d1;}

    取消input聚焦时的边框,去除ios点击时,自动添加的底色效果

    解决方案:

    input[type="text"], input[type="button"], input[type="submit"], input[type="reset"], select, textarea,button {
        /*去除ios点击时,自动添加的底色效果*/
        -webkit-tap-highlight-color: rgba(255, 255, 255, 0);
    
        /*去除焦点框*/
        outline:none;
    }
