我打算禁用表单输入。我知道disabled或readonly会执行此过程。我打算在表单上使用readonly。

我将发布代码，然后说明问题：

body,
input,
select,
textarea,
body * {
  font-family: 'Roboto', sans-serif;
  box-sizing: border-box;
}

body::after,
body::before,
input::after,
input::before,
select::after,
select::before,

textarea::before,
body *::after,
body *::before {
  box-sizing: border-box;
}

.form-radio,
.form-group {
  position: relative;
}

.form-inline>.form-group,
.form-inline>.btn {
  display: inline-block;
  margin-bottom: 0;
}

.form-group input {
  height: 1.9rem;
}

.form-group .control-label {
  position: absolute;

.form-group .bar {

        <label for="Pedi" class="control-label">Pedido</label><i class="bar"></i>
      </div>
    </div>
  </div>
</form>

问题出在CSS中，我找不到它。问题是，当我在输入中输入readonly = "true"时，仅当我单击输入并且希望使其始终可见时，该输入的值才可见

答案 0 :(得分：1)

问题是您的<input>和<label>有CSS规则，它们仅在:focus伪类中应用，听起来您希望默认应用它们而不用专注于元素。相关的样式规则似乎是：

<label>：

font-size: 0.8rem;
color: #3a3a3a;
top: -1rem;
left: 0;

和<input>：

color: #333;

只需将这些添加到针对那些没有:focus伪类的元素的CSS规则中即可：

@import url(https://fonts.googleapis.com/css?family=Roboto);
body,
input,
select,
textarea,
body * {
  font-family: 'Roboto', sans-serif;
  box-sizing: border-box;
}
body::after, body::before,
input::after,
input::before,
select::after,
select::before,
textarea::after,
textarea::before,
body *::after,
body *::before {
  box-sizing: border-box;
}

.form-radio,
.form-group {
  position: relative;

}

.form-inline > .form-group,
.form-inline > .btn {
  display: inline-block;
  margin-bottom: 0;
}

.form-group input {
  height: 1.9rem;
}

.form-group .control-label {
  position: absolute;
  pointer-events: none;
  padding-left: 0.125rem;
  z-index: 1;
  font-weight: normal;

  /* right here */
  font-size: 0.8rem;
  color: #3a3a3a;
  top: -1rem;
  left: 0;
}

.form-group .bar {
  position: relative;
  border-bottom: 0.0625rem solid #999;
  display: block;
}
.form-group .bar::before {
  content: '';
  height: 0.125rem;
  width: 0;
  left: 50%;
  bottom: -0.0625rem;
  position: absolute;
  background: #337ab7;
  -webkit-transition: left 0.28s ease, width 0.28s ease;
  transition: left 0.28s ease, width 0.28s ease;
  z-index: 2;
}
.form-group input,
.form-group textarea {
  display: block;
  background: none;
  padding: 0.125rem 0.125rem 0.0625rem;
  font-size: 1rem;
  border-width: 0;
  border-color: transparent;
  line-height: 1.9;
  width: 100%;
  -webkit-transition: all 0.28s ease;
  transition: all 0.28s ease;
  box-shadow: none;

  /* and here */
  color: #333;
}

.form-group select,
.form-group input:focus,
.form-group input:valid,
.form-group input.form-file,
.form-group input.has-value,
.form-group textarea:focus,
.form-group textarea:valid,

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<form class="text-center border border-light largura limp6" action="#!">

     <div class="h4 mb-4">CONSULTAR PEDIDO DE MANUTENÇÃO</div>
                       <div style="clear:both;"></div>
                        <div class="row">
                        <div class="col-md-4 col-xs-4">
                            <div class="form-group">
                                <input type="text" id="Pedi" name="Pedi" value="teste" readonly="true">
                                <label for="Pedi" class="control-label">Pedido</label><i class="bar"></i>
                            </div>
                        </div>
          </div>
</form>

（注意：我假设<label>和<div>之间带有标题文本的重叠在您的完整代码中不会发生，而只是此示例的副作用。否则，如果{ {1}}根本不应该显示，然后只需将其删除即可。）
