[CSS] 17. Outlines ( 외곽선, 아웃라인 )

이번에는 외곽선 속성에 대해서 알아보도록 하겠습니다.

 

아웃라인(외곽선)은 테두리와 많이 유사합니다. 그래서 준비했습니다. 

 

이 두개의 차이점:

• 외곽선은 공간을 차지하지 않습니다.

• 외곽선은 직사각형일 필요가 없습니다.

• 외곽선은 사방이 모두 똑같은 선입니다. 테두리처럼 왼쪽은 점선, 오른쪽은 직선, 이렇게 따로 설정할 수가 없습니다.

NOTE: 이 속성도 IE 6 이나 Netscape 7에서는 안된다고 하는군요. 아직도 이런 브라우저를 사용하시는 분들은 없겠지만요 ㅋ 

 

자 그럼 외곽선 관련 속성에 어떤것들이 있는지 한번 알아봅시다. 

•  outline-width

•  outline-style  

•  outline-color  

•  outline  

The outline-width Property:

The outline-width property specifies the width of the outline to be added to the box. Its value should be a length or one of the values thin, medium, or thick . just like the border-width attribute

A width of zero pixels means no outline.

<p style="outline-width:thin; outline-style:solid;"> This text is having thin outline. </p> <br /> <p style="outline-width:thick; outline-style:solid;"> This text is having thick outline. </p> <br /> <p style="outline-width:5px; outline-style:solid;"> This text is having 5x outline. </p>

 

결과는 아래와 같습니다.

This text is having thin outline. This text is having thick outline. This text is having 5x outline.

 

The outline-style Property:

The outline-style property specifies the style for the line (solid, dotted, or dashed) that goes around an element. It can take one of the following values:

• none: No border. (Equivalent of outline-width:0;)

• solid: Outline is a single solid line.

• dotted: Outline is a series of dots.

• dashed: Outline is a series of short lines.

• double: Outline is two solid lines.

• groove: Outline looks as though it is carved into the page.

• ridge: Outline looks the opposite of groove.

• inset: Outline makes the box look like it is embedded in the page.

• outset: Outline makes the box look like it is coming out of the canvas.

• hidden: Same as none.

The outline-color property allows you to specify the color of the outline. Its value should either be a color name, a hex color, or an RGB value, as with the color and border-color properties.

<p style="outline-width:thin; outline-style:solid; outline-color:red"> This text is having thin solid red outline. </p> <br /> <p style="outline-width:thick; outline-style:dashed; outline-color:#009900"> This text is having thick dashed green outline. </p> <br /> <p style="outline-width:5px;outline-style:dotted; outline-color:rgb(13,33,232)"> This text is having 5x dotted blue outline. </p>

 

결과는 아래와 같습니다.

This text is having thin solid red outline. This text is having thick dashed green outline. This text is having 5x dotted blue outline.

 

The outline Property:

The outline property is a shorthand property that allows you to specify values for any of the three properties discussed previously in any order but in a single statement.
