Answer 1

<label for="subdomain">Subdomain:</label>
<input type="text" placeholder="ExampleDomain" id="subdomain" />

    -webkit-appearance: none!important;
    color: red;
    text-align: right;
    width: 75px;
    border: 1px solid gray;

    border: 1px solid gray;
    border-right: 0px;
    outline: none;

JS小提琴为此

Answer 2

您可以通过以下方法实现此目的:

• 放置<input>在<label>与position:relative
• 给出<label>一个::after伪元素position:absolute
• 设定box-sizing的<input>到border-box
• 给<input>a padding-right等于::after伪元素的宽度

工作实例:

label, input {
    position: relative;
    display: block;
    padding-right: 76px;
    width: 170px;
    box-sizing: border-box;
}

label::after {
    content: '.' attr(data-domain);
    position: absolute;
    top: 4px;
    left: 94px;
    font-family: arial, helvetica, sans-serif;
    font-size: 12px;
    display: block;
    color: rgba(0, 0, 0, 0.6);
    font-weight: bold;
}

<label data-domain="domain.com">
<input type="text" placeholder="exampledomain" />
<label>
