I am practicing CSS and I am so confused about how can I force my div element to be center (vertically and horizontally) at my page (mean which way or ways for cross browser compatibility)?

Best regards!

解决方案

There are many methods :

1. Center horizontal and vertical align of an element with fixed measure

CSS

 <div style="width:200px;height:100px;position:absolute;left:50%;top:50%;
margin-left:-100px;margin-top:-50px;">
<!–content–>
</div>

2 . Center horizontally and vertically a single line of text

CSS

<div style="width:400px;height:200px;text-align:center;line-height:200px;">
<!–content–>
</div>  

---

3 . Center horizontal and vertical align of an element with no specific measure

CSS

<div style="display:table;height:300px;text-align:center;">
<div style="display:table-cell;vertical-align:middle;">
<!–content–>
</div>
</div>
