< img>的宽度属性与< img style =" width：..." [英] Width attribute for <img> versus <img style="width:..."
问题描述
大家好，
我想知道并理解它们之间的区别，比如说，
< img src =" [path] /ImageFilename.png"宽度= QUOT; 123"高度= QUOT; 456" alt ="">
和
< img src =" [path] /ImageFilename.png" style =" width：123px;身高：456像素;
alt ="">
从编码的角度来看，存在差异。另外，从一个网页
设计，我相信也存在差异。
为什么HTML表单会被弃用或坏？ ...对比CSS形式？

在第一种形式中，宽度和高度信息仍然存在
当CSS没有使用时。
为什么HTML表单会被弃用还是坏？
不是。你在哪里读到的？

我不记得我在哪里读过这个或谁这么说过了。
在某些情况下，最好使用CSS表格
（即style =" width：123px; height：456px;"）代码HTML
属性代码）。假设你在一个页面上有20个图像，它们都是
具有相同的宽度和高度。然后你就可以了。
img.SameDim {width：[valueX];身高：[valueY];}
但这种情况不太可能经常出现。所以，当你所有的图像都有不同的尺寸时，为什么CSS形式会更好的编码实践或带来某些好处...我可以' '$
看到任何...

对于它的价值，我不同意。
尺寸是图像的固有属性，而不是像边缘那样的b
。

Hello all,
I''d like to know and understand the difference between, say,
<img src="[path]/ImageFilename.png" width="123" height="456" alt="">
and
<img src="[path]/ImageFilename.png" style="width: 123px; height: 456px;"
alt="">
From a coding perspective, there is a difference. Also, from a webpage
design, I believe there is also a difference.
Why would the HTML form be deprecated or bad? ...versus the CSS form?

In the first form the width and height information is still present
when the CSS isn''t used.

It isn''t. Where did you read that?

I can''t remember where I read that or who said so.
There are situations where it could be better to use the CSS form
(ie. the style="width: 123px; height: 456px;") code over the HTML
attribute code). Let''s say you have 20 images on a page and they all
have the same width and height. Then you can do
img.SameDim {width: [valueX]; height: [valueY];}
but such kind of situation is not likely to appear often. So, when all
your images are of different dimensions, why would the CSS form be a
better coding practice or bring some benefits of some sort... I can''t
see any...

For what it''s worth, I don''t agree.
The size is an intrinsic property of the image, not a bit of
presentation like a margin.
