How do I align two inline blocks of text horizontally?

Question

When I minimize the browser window to the left the sidebar text goes down. When I minimize it to the right the article text goes down. Is it possible to align them on the top? Here is the jsfiddle

<div id="wrapper">
<aside></aside>
<section></section>
</div>

#wrapper{
  width: 100%;
  padding: 10px;
}

section {
  display: inline-block;
  width: 70%;
  height: 400px;
}

aside {
  display: inline-block;
  width: 25%;
  height: 400px; 
}

Thank you!

Answer 1

Have you tried vertical-align option?

aside {
  display: inline-block;
  width: 25%;
  height: 400px; 
  vertical-align: top;
}

I wouldn't use inline-block for complex elements that have many child elements in them.. if you want to make a columnar layout, either use floats, or flexbox.

#wrapper{
  width: 100%;
  padding: 10px;
}

section {
  float: left;
  width: 70%;
  height: 400px;
}

aside {
  float: left;
  width: 25%;
  height: 400px; 
}

<div id="wrapper">
      <aside>
   
        <h2>Sidebar</h2>
          
        <ol>
          <li>first item</li>
          <li>second item</li>
          <li>third item</li>
        </ol>
        
      </aside>
      
      <section>
      
        
          <h2>
             Article Title
          </h2>

depending on your browser support requirement, you can use flexbox

#wrapper{
  width: 100%;
  height: 400px;
  padding: 10px;
  display: flex;
  align-items: center;
  justify-content: center;
}
