text-align:center not working with div elements
提问by Doctor Parameter
I've been searching for about 45 minutes and couldn't find a solution for my issue here. I want my gallery class divs (these will get created dynamically) to align them selves in the center of the gallery_container div using only css rules. I'm learning so any explanation would be helpful!
我已经搜索了大约 45 分钟，但在这里找不到解决我的问题的方法。我希望我的画廊类 div（这些将动态创建）仅使用 css 规则将它们自己对齐到 gallery_container div 的中心。我正在学习，所以任何解释都会有帮助！
Thanks in advance!
提前致谢！

This can be done with by using an inline-blockdisplay, the float:leftwill always send the elements to their furthest left possible.
这可以通过使用inline-block显示器来完成，float:left它将始终将元素发送到尽可能最左侧。
.gallery {
text-align: left;
border-style: solid;
border-width:3px;
border-top-left-radius: 40px;
border-bottom-right-radius: 40px;
background:yellow;
width:335px;
padding:20px;
/*float:left; remove this*/
margin:15px;
/*add this*/
display:inline-block;
position:relative;
}
