2 holes in JS about line breaks

The first place to pay attention to the use of Li in Ul/ol

1, <ul id= "Banner_indicator" ><li></li><li></li><li></li><li>< /li></ul>

2, <ul id= "Banner_indicator" >






When using the following calling method

var Indicatortag = document.getElementById ("Banner_indicator");
var linodes = indicatortag.childnodes;

Summary: call 1 o'clock to get all the Li members, but the call Method 2 o'clock can only get the first row of Li.

The second one is about the details of the div wrapping, which I believe many people have encountered

1. <div id= "Parent" >









When there is always a gap between the first inner Div, even if the following CSS parameters are set in the main div style

#parent {





The result is no change, or there is a gap, but the gap disappears after using the second style, summary: The default is to add a space when using div wrapping.
