Question

        <form class="navbar-form" >
            <div class="input-group">
              <input type="text" class="form-control search-form" placeholder="Search">
               <span class="input-group-btn"><button type="submit" class="btn btn-primary search-btn"><i class="fa fa-search"></i>
                </button></span>
            </div>
        </form>


.search-form {
border-radius: 30px 0px 0px 30px;
background-color: transparent;
border: 1px solid #ffffff;
border-right: 0px;
}
.search-btn {
border-radius: 0px 30px 30px 0px;
cursor:pointer;
background-color: transparent;
border: 1px solid #ffffff;
border-left: 0px;
}

如何将.search-btn的边框与.form-control相同，因为我专注于.form-control类？当我专注于输入字段时，我想制作输入字段的边框颜色和搜索按钮＃fd9128。
