Today, I would like to share with you how css increases the width of # box to 200 pixels. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

If the setting function does not return anything (for example. Function (index, style) {}), or if undefined is returned, the current value will not change. It is useful only when certain conditions are met and selective setting values are met.

Example:

Example: change the color of some paragraphs to red through the mouseover event.

P {color:blue; width:200px; font-size:14px;}

Just roll the mouse over me.

Or me to see a color change.

$("p") .Mouseover (function () {

(this) .css ("color", "red")

})

Example: increase the width of # box to 200 pixels

# box {background: black; color: snow; width:100px; padding:10px;}

Click me to grow

$("# box"). One ("click", function () {

(this) .css ("width", "+ = 200")

})
