How to make the height of the picture automatically unchanged in CSS and how to limit the width and length? _html/css_WEB-ITnose
The height of the image changes with the height of the image, that is, there is no limit. There are two effects you want for the width: the width length is 1200PX, or it automatically exceeds the browser.
There are two desired effects:
The first one is that the width and length change with the picture. If the width exceeds 1500PX, a frame below the browser will appear and can be pulled horizontally. This seems to be more difficult.
The second method is to change the width of the image to 1200PX and the height remains unchanged.
But I found that what I wrote had no effect. DEDE calling code:
<DIV class=col_main4><DIV class=gallery_list5><DIV id=mainNewsTitles><H1>{dede:field.title/}</H1></DIV><DIV class=contentbox><DIV class=mainNewsInfo>作者：{dede:field.writer/} 发布时间：{dede:field.pubdate function="MyDate('Y-m-d H:i',@me)"/}</DIV><div align="center"></div><DIV class=NewsContent>{dede:field.body/}<p class="textpage" align="center">{dede:pagebreak/}</p><p></p>CSS code:
.col_main4 img{ width: 1200px;}.gallery_list5 img{ BORDER-RIGHT: #dfdfdf 1px solid; MARGIN-TOP: 10px; FONT-SIZE: 12px; OVERFLOW: hidden; width: 1200px;}This way the image width is still the same There is no reduction, it has exceeded 1200PX,
Remove width: 1200px; the image width does not exceed the browser 1440 and can be stretched horizontally. This effect
The excess part is covered by the DIV layer, but cannot exceed the DIV layer.
CSS newbie, please give an expert answer. Thank you

yong Wrap it in a container This picture, and then set the width of the container to a fixed width, the height to auto, and then overflow: hidden; it will be OK. You can set the picture how you want. I still don’t understand how to send a message to the site. I don’t quite understand what you said. I can’t. Help the poster

It seems a bit confusing
CSS limits the width of the image Directly to width:1200px; can be limited.
If the parent element or ancestor element of the image defines a width less than 1200 and uses OVERFLOW: hidden;
then its child elements will be hidden as long as they exceed the width of 1200.
.col_main4 img{
width: 1200px;
}
.gallery_list5 img{
BORDER-RIGHT: #dfdfdf 1px solid; MARGIN-TOP: 10px; FONT -SIZE: 12px; OVERFLOW: hidden;
width: 1200px;
}
defines the width of the image as 1200PX, but the image is not reduced to 1200PX, so it has no effect, { dede:field.body/} is the tag to get the article content,
.NewsContent { MARGIN: 5px; LINE-HEIGHT: 120%; TEXT-ALIGN: center;}.NewsContent IMG { BORDER-TOP-STYLE: none; BORDER-RIGHT-STYLE: none; BORDER-LEFT-STYLE: none; BORDER-BOTTOM-STYLE: none; width:1200px;}Added width: 1200px After going up, I found that it still has no effect. Thank you for your answer
I’m a little confused
CSS limits the width of the image. Just limit it to width: 1200px;.
If the parent element or ancestor element of the image defines a width less than 1200 and uses OVERFLOW: hidden;
then its child elements will be hidden as long as they exceed the width of 1200.
Hello,
.NewsContent {
MARGIN: 5px; LINE-HEIGHT: 120% ; TEXT-ALIGN: center;
}
.NewsContent IMG {
BORDER-TOP-STYLE: none; BORDER-RIGHT-STYLE: none; BORDER-LEFT-STYLE: none; BORDER-
BOTTOM-STYLE: none; width:1200px;height:auto;overflow:hidden;
}
After adding width:1200px;height:auto;overflow:hidden; I found that it has no effect. I don’t understand what you mean. What does it mean to wrap this image in a container? The {dede:field.body/} tag calls out the text of the article. My text is all pictures, so the CSS is written like this:
NewsContent IMG {
BORDER-TOP-STYLE: none; BORDER-RIGHT-STYLE: none; BORDER-LEFT-STYLE: none; BORDER-
BOTTOM-STYLE: none; width:1200px;height:auto;overflow: hidden;
}
I don’t know if .NewsContent IMG has no effect on the image obtained by {dede:field.body/}.
My current thinking is quite confusing, please give me some advice, thank you.
