input[type="text"] element cannot display as inline but inline-block

As the title described, I can't set the style of a input[type="text"] element to display: inline.

After I apply the styles, it still behaves like display: inline-block

I tried the codes below.

.box {
  border: 2px solid black;
  padding: 5px;
  margin: 15px;
}

.inline {
  border: 2px solid rebeccapurple;
  padding: 10px;
  display: inline;
}

<body>
  <div class="box">
    <input class="inline" type="text" name="" id="" value="input">
  </div>
  <div class="box">
    <span class="inline">span</span>
  </div>
</body>

I google this question but get nothing.

I've check the dev tools (in Edge), it shows the input[type="text"] element actually has the display: inline property as its style.

but it just display as a inline-block element, and not behaved like the span (which behaved like a inline element).

Solution

<input> is a special element. In some cases they are considered as "replaced element" and in other cases, their display is always inline-block even if you explicitly change it. In all the cases, an <input> will behave as inline-block and never as an inline

Below is the computed value of display. In your case, it's inline-block even if inline is specified
