Introduction to the JavaScript Web

This is my first blog, starting from today to record what I learned, I hope I can learn more and more.

JavaScript output: document.write () Four ways:

1. Direct output double quotation mark content document.write ("");

2. Output variable name, such as: Var mychar= "Hello";d ocument.write (MyChar);

3. Use the Plus "+": document.write (mychar+ "Hello");

4. Output HTML tags, tagged with double quotes "": document.write (mychar+ "<br/>"); I just didn't think of this, and went back to see it again, really slag orz!

Add the width of the CSS layout or the height of the adaptive, can be set by a percentage.

What do you mean by self-adaptation? is when you drag the browser window, zoom in or out, it will still be the same as the browser window before the layout.

Using Position:absolute to achieve the adaptive width three column layout:

Design a three-column layout, left fixed width 200px,height:400px, fixed width:300px,height:400px on the right, and adaptive (with margin) in the middle. If you set left,right with float it will not achieve the desired effect.

. left{width:200px;height:400px;background-color:red;position:absolute;top:0;left:0;}

. mid{height:400px;background-color:blue;margin:0 310px 0 210px;}

. right{width:300px;height:400px;background-color:orange;position:absolute;right:0;top:0;}
