Javascript 无法在图像上居中放置标题标记
我试着将图片和它们的文章标题对齐,但不知怎么的,图片和标题的左侧部分被一小段边距切断了。我尝试了很多方法,但都无法将标题标记居中。 我试着把图片和他们的文章标题放在中间,我使用的脚本如下Javascript 无法在图像上居中放置标题标记,javascript,jquery,html,css,centering,Javascript,Jquery,Html,Css,Centering,我试着将图片和它们的文章标题对齐,但不知怎么的,图片和标题的左侧部分被一小段边距切断了。我尝试了很多方法,但都无法将标题标记居中。 我试着把图片和他们的文章标题放在中间,我使用的脚本如下 <script type='text/javascript'>//<![CDATA[ /** this script was written by Confluent Forms LLC http://www.confluentforms.com for the BlogXpertise we

/我不确定如何编辑脚本,但在chrome控制台上,我做了以下操作来修复它
拆下柱体下方的右侧浮子
偏移图像本身
文本已经居中,问题在于元素的定位

嗨@brygiger!我试着用这个做后期图像偏移。后期图像{left:15px;right:15px;position:absolute;}成功了,但现在右侧部分被切断了!对css有什么建议吗?“这个”?很抱歉编辑,查看其余的评论。给我一个sectry.postImage img{left:5px;bottom:10px;}您应该移动img标记,而不是图像中心的父标记\是的,成功了但是第一张图片的标题被剪掉了一点!有什么解决方案吗?嗯,div对于文本来说太小了,所以你要么把包含div的部分变大(更高),然后把文本包装起来,要么把文本变小。
.postImage img {left: -6px; bottom: 10px;}
.post-body a {float:none;}
