[PHP]因此，我正在进行一个项目，在该项目中，我必须显示表中的元素（一个图像和3个文本元素），然后在下面提供一个“注释”空间。然而，当在网站上检查我的代码时，我的输出回音没有对齐，在检查元素时，我的表单关闭标记在php echo中不起作用？表元素在编译时相互溢出。我的'有什么问题；评论'；输入？,php,html,css,mysql,database,Php,Html,Css,Mysql,Database,[PHP]因此，我正在进行一个项目，在该项目中，我必须显示表中的元素（一个图像和3个文本元素），然后在下面提供一个“注释”空间。然而，当在网站上检查我的代码时，我的输出回音没有对齐，在检查元素时，我的似乎是空的，并且所有代码都已迁移到新的。此外，我在底部的addcomment表单，即使我认为是一个格式正确的close标记，也不起作用，最终将下面的所有代码分组到上面的中。我的代码如下： <html> <font face="georgia" color="#4c4c4c">
