1. Overview of CSS display

No ADS
CSS display is used in the following situations:
1 - CSS {display: none}
CSS {display:none} is used to hide an element and release the space that it occupies.
2 - CSS {display: block | inline | inline-block}
Use CSS display with one of the block, inline, inline-block values to make the element treated as a Block element, inline element, or inline-block element.
3 - CSS {display: grid | flex | ... }
Use CSS display with other values (grid, inline-grid, flex, ...) to set the layout for the children of the current element. For example, CSS {display: grid | inline-grid} dividing the surface of the current element into a grid, consisting of many rows and columns, its children will be arranged on these grid cells.

2. CSS {display: none}

CSS {display:none} is used to hide an element and release the space that it occupies. To redisplay this element, use CSS {display:block | inline | inline-block} or remove CSS display.

             var myImage = document.getElementById("myImage");
             var displayValue = myImage.style.display; 
             if(!displayValue) {
                 myImage.style.display = "none";
             } else {
                 // Remove CSS display.
                 myImage.style.display = null;
                 // OR Set to: block|inline|inline-block.

CSS {visibility:hidden} makes an element become invisible, but it doesn't release the space that the element occupies.

3. CSS {display:block}

Use CSS {display:block} for an element to make it treated as a Block-level element.
  • Some default elements are a block element, for example <div>, <hr>, ...
  • Some other elements are by default Inline elements, for example <span>, your can use CSS {display:block} for them to turn it into a block element.
A block element is always displayed as a rectangle. The browser automatically adds line breaks before and after of this element.
Example: Apply CSS {display:block} to the <span> element to turn it into a block element:
display-block-example.html
<!DOCTYPE html>
<html>
   <head>
      <title>CSS {display:block}</title>
      <meta charset="UTF-8"/>
      <script>
          function setDisplayBlock()  {
             var mySpan = document.getElementById("mySpan");
             mySpan.style.display = "block";
          }
          // Use default display.
          function removeDisplay()  {
             var mySpan = document.getElementById("mySpan");
             mySpan.style.display = null;
          }
      </script>
   </head>
   <body>
       <h2>CSS {display:block}</h2>
       <button onClick="setDisplayBlock()">Set {display:block}</button>
       <button onClick="removeDisplay()">Remove display property</button>
       <div style="padding:5px; margin-top:10px; background:#eee;">
           <img src="../images/flower.png" id= "myImage"/>

           <span id="mySpan" style="background:yellow">Apollo 11</span> was the
           spaceflight that landed the first humans,
           Americans Neil Armstrong and Buzz Aldrin,
           on the Moon on July 20, 1969, at 20:18 UTC.
           Armstrong became the first to step onto the lunar
           surface 6 hours later on July 21 at 02:56 UTC.
       </div>
   </body>
</html>

4. CSS {display: inline}

Use CSS {display:inline} for an element to make it treated as a Inline element.
  • Some elements are by default inline elements, for example, <span>, <strong>, ...
  • Some other elements are by default block elements, for example, <div>, for which you can use CSS {display:inline} to turn them into inline elements.
An inline element, in many cases, are not a rectangle. It may lie on multiple lines.

Americans Neil Armstrong and Buzz Aldrin,

             myDiv.style.display = "inline";
          }
          // Use default display.
          function removeDisplay()  {
             var myDiv = document.getElementById("myDiv");
             myDiv.style.display = null;
          }
      </script>

No ADS
Use CSS {display:inline-block} for element to make it treated as an Inline-block element.
"Inline-block element" is a rectangle. The browser will not automatically add line breaks before and after this element, which makes inline-block elements possible on the same line.
display-inline-block-example.html
<!DOCTYPE html>
<html>
   <head>
      <title>CSS {display:inline-block}</title>
      <meta charset="UTF-8"/>
      <style>
          div {
            background: yellow;
            padding: 5px;
            margin: 5px;
          }
      </style>
   </head>
   <body>
       <h2>CSS {display:inline-block}</h2>
       <div style="display:inline-block">

       </div>
       <div style="display:inline-block">

   </body>
</html>
