Title rewritten as: How to align list items with text above?

Question

Using invalid HTML I can get the look I want, but not using valid HTML. Is there CSS that allows me to configure <FIGURE> or <FIGCAPTION> to simulate the effect of <SPAN>?

I want the look of it to be on the left and the valid HTML on the right.

Invalid HTML:

body {
  margin: auto;
  padding: 0 5px 0 5px;
  font-family: Tahoma, Verdana, sans-serif;
  font-size: 12pt;
  background-color: black;
  color: white;
}

<UL>
  <SPAN style="font-weight: bold; text-decoration: underline; color: lemonchiffon">颜色代码指南</SPAN>
  <LI>
    <SPAN style="color: DarkCyan">注释</SPAN>
  </LI>
  <LI>
    <SPAN style="color: Coral">处理器指令</SPAN>
  </LI>
  <LI>
    <SPAN style="color: HotPink">#ifndef name</SPAN>
  </LI>
  <LI>
    <SPAN style="color: PaleTurquoise">库包含</SPAN>
  </LI>
  <LI>
    <SPAN style="color: DarkSalmon">用户定义的包含</SPAN>
  </LI>
  <LI>
    <SPAN style="color: Gold">库函数</SPAN>
  </LI>
  <LI>
    <SPAN style="color: DarkKhaki">初始化函数</SPAN>
  </LI>
  <LI>用户定义的函数</LI>
  <LI>
    <SPAN style="color: DodgerBlue">关键字</SPAN>
  </LI>
  <LI>
    <SPAN style="color: Red">重要符号</SPAN>
  </LI>
</UL>

Valid HTML:

body {
  margin: auto;
  padding: 0 5px 0 5px;
  font-family: Tahoma, Verdana, sans-serif;
  font-size: 12pt;
  background-color: black;
  color: white;
}

<FIGURE>
  <FIGCAPTION>
    <SPAN style="font-weight: bold; text-decoration: underline; color: lemonchiffon">颜色代码指南</SPAN>
  </FIGCAPTION>
  <UL>
    <LI>
      <SPAN style="color: DarkCyan">注释</SPAN>
    </LI>
    <LI>
      <SPAN style="color: Coral">处理器指令</SPAN>
    </LI>
    <LI>
      <SPAN style="color: HotPink">#ifndef name</SPAN>
    </LI>
    <LI>
      <SPAN style="color: PaleTurquoise">库包含</SPAN>
    </LI>
    <LI>
      <SPAN style="color: DarkSalmon">用户定义的包含</SPAN>
    </LI>
    <LI>
      <SPAN style="color: Gold">库函数</SPAN>
    </LI>
    <LI>
      <SPAN style="color: DarkKhaki">初始化函数</SPAN>
    </LI>
    <LI>用户定义的函数</LI>
    <LI>
      <SPAN style="color: DodgerBlue">关键字</SPAN>
    </LI>
    <LI>
      <SPAN style="color: Red">重要符号</SPAN>
    </LI>
  </UL>
</FIGURE>

Answer 1

You should check the user agent value using development tools

For example, the first element under TD is ul or figure. The standards in Chrome are as follows:

ul {
    display: block;
    list-style-type: disc;
    margin-block-start: 1em;
    margin-block-end: 1em;
    margin-inline-start: 0px;
    margin-inline-end: 0px;
    padding-inline-start: 40px;
}
figure {
    display: block;
    margin-block-start: 1em;
    margin-block-end: 1em;
    margin-inline-start: 40px;
    margin-inline-end: 40px;
}

So if you want to keep figure with ul layout, add figure in your style, override the attributes that break the layout, and add the required attributes.

Answer 2

Just add some styles to reset the default styles.

ul {
  padding: 0; 
  margin: 0;
  list-style-position: inside;
}

<FIGURE>
  <FIGCAPTION>
    <SPAN style="font-weight: bold; text-decoration: underline; color: lemonchiffon">颜色代码指南</SPAN>
  </FIGCAPTION>
  <UL>
    <LI>
      <SPAN style="color: DarkCyan">注释</SPAN>
    </LI>
    <LI>
      <SPAN style="color: Coral">处理器指令</SPAN>
    </LI>
    <LI>
      <SPAN style="color: HotPink">#ifndef 名称</SPAN>
    </LI>
    <LI>
      <SPAN style="color: PaleTurquoise">库包含</SPAN>
    </LI>
    <LI>
      <SPAN style="color: DarkSalmon">用户定义的包含</SPAN>
    </LI>
    <LI>
      <SPAN style="color: Gold">库函数</SPAN>
    </LI>
    <LI>
      <SPAN style="color: DarkKhaki">初始化函数</SPAN>
    </LI>
    <LI>用户定义的函数</LI>
    <LI>
      <SPAN style="color: DodgerBlue">关键字</SPAN>
    </LI>
    <LI>
      <SPAN style="color: Red">重要符号</SPAN>
    </LI>
  </UL>
</FIGURE>
