CSS Resizing
The resize property specifies if (and how) an element should be resizable by the user.
This div element is resizable by the user!
To resize: Click and drag the bottom right corner of this div element.

The following example lets the user resize only the width of a <div> element:

Example

div
{
 
resize: horizontal;
 
overflow: auto;
}

The following example lets the user resize both the height and width of a <div> element:

overflow: auto;
}

In many browsers, <textarea> is resizable by default. Here, we have used the resize property to disable the resizability:

Example

textarea {  resize: none;}

CSS Outline Offset
The outline-offset property adds space between an outline and the edge or
border of an element.
This div has an outline 15px outside the border edge.

Note: Outline differs from borders! Unlike border, the outline is
drawn outside the element's border, and may overlap other content. Also, the outline is
NOT a part of the element's dimensions; the element's total width and height
is not affected by the width of the outline.

The following example uses the outline-offset property to add space
between the border and the outline:

Example

div.ex1 {  margin: 20px;  border:
1px solid black;  outline: 4px solid red; 
outline-offset: 15px;} div.ex2 {  margin: 10px;  border: 1px solid black;  outline: 5px dashed blue;  outline-offset: 5px;}
