使多个段落显示为一个

Question

我正在尝试制作一个工具，可以根据您的鞋码计算您需要多大的滑板。代码如下：

const shoeSizeInput = document.getElementById('shoeSize')
      const shoeSizeResult = document.getElementById('resultSize') 

shoeSizeInput.addEventListener('input', (event) => {
  const shoeSize = parseInt(event.target.value) 
  let boardSize = '?'

  switch (true) {
    case 0 <= shoeSize && shoeSize <= 7:
      boardSize = '7.75'
      break;
    case shoeSize === 8 || shoeSize === 9:
      boardSize = '8'
      break;
    case shoeSize === 10 || shoeSize === 11:
      boardSize = '8.25'
      break;
    case shoeSize === 12 || shoeSize === 13:
      boardSize = '8.38'
      break;
    case 14 <= shoeSize && shoeSize <= 20:
      boardSize = '8.5'
      break;
  }
  shoeSizeResult.textContent = boardSize 
})

<div class="board-tool">
    <p>Most people pick their board size by prefrence but I will make a tool below to choose a board size that will fit your shoe size best. The most popular board sizes are 7.75, 8, 8.25, 8.38, and 8.5.</p>
    <label>If your shoe size is:</label><input id='shoeSize' type="number" class="shoe">
    <p id="resultSize"></p><p>should be your ideal board size.</p>
  </div>

.shoe {
  width: 50px;
  height: 15px;
  border-radius: 5px;
  margin-left: 10px;
}
.board-tool {
  font-size: 1.5rem;
}

所有代码都有效，但问题是第一段、标签和之后的段落都在不同的行上，但我想组织它，使其看起来像一个段落，例如： 如果你的鞋码是：12，8.25 将是理想的板码。

Answer 1

有几种方法可以解决您的问题。但我认为首先是对 HTML 元素有一个基本的了解。

<p>（段落）元素是块项目，这意味着默认情况下，它们的宽度是其包含元素的 100%，并且它们具有默认的顶部和底部边距，旨在提供元素之间的一些默认间距。

<span> 元素是内联的。它们一个接一个地连续运行，这样它们就可以作为一个段落来阅读。

但是，现在事情要先进得多，并且很有可能使用样式和类规则将 <p> 重新定义为 <span>，反之亦然，如下面的 sn-p 所示。

虽然我不建议养成这种习惯，但可以做到。跟随您的代码的示例 div 使用浅灰色虚线边框，因此您可以看到块与内联元素的默认宽度

const shoeSizeInput = document.getElementById('shoeSize')
const shoeSizeResult = document.getElementById('resultSize')

shoeSizeInput.addEventListener('input', (event) => {
  const shoeSize = parseInt(event.target.value)
  let boardSize = '?'

  switch (true) {
    case 0 <= shoeSize && shoeSize <= 7:
      boardSize = '7.75'
      break;
    case shoeSize === 8 || shoeSize === 9:
      boardSize = '8'
      break;
    case shoeSize === 10 || shoeSize === 11:
      boardSize = '8.25'
      break;
    case shoeSize === 12 || shoeSize === 13:
      boardSize = '8.38'
      break;
    case 14 <= shoeSize && shoeSize <= 20:
      boardSize = '8.5'
      break;
  }
  shoeSizeResult.textContent = boardSize
})

.shoe {
  width: 50px;
  height: 15px;
  border-radius: 5px;
  margin-left: 10px;
}

.board-tool {
  font-size: 1.5rem;
}
/* End OP CSS */

/* Begin Example CSS */

.d-inline {
  display: inline;

.d-block {

.m-none {

.mt {

.mtb {

.b {

Answer 2

第 1 步：

将.board-tool 更改为display: flex

第 2 步：

将.board-too 更改为flex-wrap: wrap 和align-items: center

第 3 步： 给你的最后一段margin-left 10px

代码：

CSS：

.shoe {
  width: 50px;
  height: 15px;
  border-radius: 5px;
  margin-left: 10px;
}

.board-tool {
  font-size: 1.5rem;
  display: flex;
  flex-wrap: wrap;
  align-items: center;
}

.resultLabel {
  margin-left: 10px;
}

HTML：

    <div class="board-tool">
    <p>Most people pick their board size by prefrence but I will make a tool below to choose a board size that will fit
        your shoe size best. The most popular board sizes are 7.75, 8, 8.25, 8.38, and 8.5.</p>
    <label>If your shoe size is:</label><input id='shoeSize' type="number" class="shoe">
    <p id="resultSize"></p>
    <p class="resultLabel">should be your ideal board size.</p>
</div>

javascript没有变化

Answer 3

p 元素是“段落”，因此默认情况下会开始一个换行符。

您可以将这些 p 元素更改为 span 元素。

const shoeSizeInput = document.getElementById('shoeSize')
const shoeSizeResult = document.getElementById('resultSize')

shoeSizeInput.addEventListener('input', (event) => {
  const shoeSize = parseInt(event.target.value)
  let boardSize = '?'

  switch (true) {
    case 0 <= shoeSize && shoeSize <= 7:
      boardSize = '7.75'
      break;
    case shoeSize === 8 || shoeSize === 9:
      boardSize = '8'
      break;
    case shoeSize === 10 || shoeSize === 11:
      boardSize = '8.25'
      break;
    case shoeSize === 12 || shoeSize === 13:
      boardSize = '8.38'
      break;
    case 14 <= shoeSize && shoeSize <= 20:
      boardSize = '8.5'
      break;
  }
  shoeSizeResult.textContent = boardSize
})

.shoe {
  width: 50px;
  height: 15px;
  border-radius: 5px;
  margin-left: 10px;
}

.board-tool {
  font-size: 1.5rem;
}

<div class="board-tool">
  <p>Most people pick their board size by prefrence but I will make a tool below to choose a board size that will fit your shoe size best. The most popular board sizes are 7.75, 8, 8.25, 8.38, and 8.5.</p>
  <label>If your shoe size is:</label><input id='shoeSize' type="number" class="shoe">
  <span id="resultSize">?</span><span> should be your ideal board size.</span>
</div>
