难以在 HTML 表单中对齐输入字段

Question

问题：

我有一个表单，其标签和输入字段在同一行上彼此相邻，但由于标签的宽度不完全相同，因此输入字段未对齐。 我想将标签更改为相同的宽度，以便输入字段彼此垂直排列。 下面链接的图片说明了这个问题。 我试图为文本设置宽度，但它没有改变任何东西。 link to image 1 Link to image 2

  text-align: center;
  position: relative;

      </fieldset>

    </form>

Answer 1

希望这就像您正在尝试做的事情。我对包含标签和输入字段的.col 元素应用了一些样式。特别是，我使用 flexbox 来正确定位标签和输入字段。

#UpdateForm {
  text-align: center;
  position: relative;
  margin-top: 2vw;
}

.col {
  display: flex;
  align-items: center;
  padding: 10px 0;
}

.inputText {
  font-size: 30px;
  margin-right: 2vw;
  font-weight: 600;
  text-align: right;
  width: 40%;
}

#UpdateForm fieldset {
  background: white;
  border: 0 none;
  border-radius: 0px;
  box-shadow: 0 0 15px 1px rgba(0, 0, 0, 0.4);
  padding: 40px 30px;
  box-sizing: border-box;
  width: 60%;
  left: 50%;
  transform: translate(-50%, 0%);
  /*stacking fieldsets above each other*/
  position: relative;
}

/*inputs*/

#UpdateForm input,
#UpdateForm textarea,
#UpdateForm select {
  padding: 20px;
  border: 1px solid #ccc;
  border-radius: 0px;
  box-sizing: border-box;
  font-family: montserrat;
  color: #2C3E50;
  font-size: 25px;
  flex-grow: 1;
}

#UpdateForm input:focus,
#UpdateForm textarea:focus,
#UpdateForm select {
  -moz-box-shadow: none !important;
  -webkit-box-shadow: none !important;
  box-shadow: none !important;
  border: 1px solid #c7aa8b;
  outline-width: 0;
  transition: All 0.5s ease-in;
  -webkit-transition: All 0.5s ease-in;
  -moz-transition: All 0.5s ease-in;
  -o-transition: All 0.5s ease-in;
}
