HTML-CSS : Exercise-26 with Solution

Using HTML, CSS vertically and horizontally centers a child element within its parent element, using display: table.

Use display: table to make the .center element behave like a <table> element.
Set height and width to 100% to make the element fill the available space within its parent element.
Use display: table-cell on the child element to make it behave like a <td> elements.
Use text-align: center and vertical-align: middle on the child element to center it horizontally and vertically.
The outer parent (.container) must have a fixed width and height.

HTML Code:

</head>
<body>
<div class="w3rcontainer">
  <div class="center"><span>w3resource.com</span></div>
</div>

HTML-CSS: Tips of the Day

What is the difference between id and class in CSS, and when should I use them?

Example:

<div id="header_id" class="header_class">
Text
</div>

#header_id {font-color:#fff}
.header_class {font-color:#000}

(Note that CSS uses the prefix # for IDs and . for Classes.)

However color was an HTML 4.01 <font> tag attribute deprecated in HTML 5. In CSS there is no "font-color", the style is color so the above should read:

Example:

<div id="header_id" class="header_class">
Text
</div>

#header_id {color:#fff}
.header_class {color:#000}

The text would be white.
