CSS User Interface

CSS Resizing

The resize property defines if (and how) an element must be resizable by the user.

The below following example illustrates the user resize only the width of a <div> element

HTML
				
					<h1>The resize Property</h1>
<div>
  <p>Let the user resize only the width of this div element.</p>
  <p>To resize: Click and drag the bottom right corner of this div element.</p>
</div>
				
			
CSS
				
					div {
  border: 2px solid;
  padding: 20px; 
  width: 300px;
  resize: horizontal;
  overflow: auto;
}
				
			

Output

resize property css

The example enables the user to resize only the height of a <div> element

HTML
				
					<h1>The resize Property</h1>
<div>
  <p>Let the user resize only the height of this div element.</p>
  <p>To resize: Click and drag the bottom right corner of this div element.</p>
</div>
				
			
CSS
				
					div {
  border: 2px solid;
  padding: 20px; 
  width: 300px;
  resize: vertical;
  overflow: auto;
}
				
			

Output

resize with height css

The example enables the use to resize both the height and width of a <div> element:

HTML
				
					<h1>The resize Property</h1>
<div>
  <p>Let the user resize both the height and the width of this div element.</p>
  <p>To resize: Click and drag the bottom right corner of this div element.</p>
</div>
				
			
CSS
				
					div {
  border: 2px solid;
  padding: 20px; 
  width: 300px;
  resize: both;
  overflow: auto;
}
				
			

Output

resize with height

By default, <textarea> is resizable by the browser. The resize property  is used to disable the resizability:

HTML
				
					<h1>The resize Property</h1>
<p>In many browsers, textarea elements are resizable by default. In this example, we have used the resize property to disable the resizability:</p>
<textarea id="test">Textarea - Not resizable</textarea>
<br><br>
<textarea>Textarea - Resizable (default)</textarea>
				
			
CSS
				
					textarea#test {
   resize: none;
}
				
			

Output

resize with textarea

CSS Outline Offset

The outline-offset property is used to add space between an outline and the edge or border of an element.

The example defines the outline-offset property to use the space between the border and the outline:

HTML

				
					<h1>The outline-offset Property</h1>
<div class="ex1">This div has a 4 pixels solid red outline 15 pixels outside the border edge.</div>
<br>
<div class="ex2">This div has a 5 pixels dashed blue outline 5 pixels outside the border edge.
</div>
				
			
CSS
				
					.newspaper {
  column-count: 3;
  column-gap: 40px;
  column-rule-style: solid;
  column-rule-width: 1px;
  column-rule-color: lightblue;
}

				
			

Output

outline-offset
