htmlドロップダウンメニューで、サブテキストをマーキングするために、部分テキストを右側に揃える方法

Question

サブドロップダウンメニューのマーカーを作成したいと思います。 私は以下を作成しました。

Iは、次のレベルのサブメニューがあることを示すためにfont-awesomeのアイコンを挿入しました。このアイコンを右に揃えたい場合、最善の方法は何ですか？ CSSにクラスを追加するか、ただalign="right"を使用しますか？ここで

はコードです：

<div class="menuSection"> 
    <div class="menuItem" rendercondition="[Relatics.Portallink Sequence='410' Get='Visibility' ExpectedResult='Visible']"> 
     <div class="dropdown"> 
      <button class="dropbtn"><i class="fa fa-random fa-3x" aria-hidden="true"></i><br> [Relatics.Portallink Sequence='400' Get='Name']</button> 
       <div class="dropdown-content"> 
        <ul> 
         <li><a href="[Relatics.Portallink Sequence='410' Get='Url']" target="Main"><i class="fa fa-bolt fa-2x" aria-hidden="true"></i>&nbsp [Relatics.Portallink Sequence='410' Get='Name'] <i class="fa fa-play-circle fa-1x"></a> 
          <ul> 
           <li><a href="[Relatics.Portallink Sequence='411' Get='Url']" target="Main"><i class="fa fa-level-down fa-2x" aria-hidden="true"></i>&nbsp [Relatics.Portallink Sequence='411' Get='Name'] </a></li> 
           <li><a href="[Relatics.Portallink Sequence='412' Get='Url']" target="Main"><i class="fa fa-table fa-2x" aria-hidden="true"></i>&nbsp [Relatics.Portallink Sequence='412' Get='Name'] </a></li>

       </div>

Answer 1

は、クラスを追加し、CSSでfloat: right;を使用して私には最良の方法のように思えます。

.listitem { 
 
    background: yellow; 
 
    width: 200px; 
 
} 
 

 
.icon { 
 
    float: right; 
 
}

<div class="listitem">List item<i class="icon">Icon</i></div>
