                padding-left: 10px;
            }
        }
        //select
        .selects:after{
            content: "";
            width: 13px;
            height: 12px;
            background: url("http://p6c8y8c2e.bkt.clouddn.com/index/zhongwenyingwen@2x.png");
            background-repeat: no-repeat;
            background-size:100%;
            position: absolute;
            right: 0;
            top: 45%;
            pointer-events: none;
        }

< vue > 

                <div class="selects">
                    <Select v-model="languages" class="head-select" @on-change="changelang">
                        <Option @click="changeref()" v-for="item in languageList" :value="item.id" :key="item.id">{{ item.name }}</Option>
                    </Select>
                </div>

what result do you expect? What is the error message actually seen?

Iview

rewrite a class class, write on the tag, cover it not on the line, really can not write a style

you did not overwrite it may be because your class does not really cover the style that tag. I use iview, although we only use one line when we use it, but there are many levels when we look at the real html, please check it. There are also some inline styles that are used directly, so yours does not take effect
