Not sure if this is even remotely possible, but asking anyway. I have a div with a fixed height and width that I cannot edit. I can, however, add in child elements. Is there a way to only use child elements to shrink the size of the parent?
And I can only use inline css, with no js or jquery.
Since the original div is empty (see comments), instead of setting the default fixed width/height on all states of the div - you could set these properties only for the empty state of the div using the empty pseudo class.
This way, when the div gets children added - those original fixed widths don't apply anymore.
div:empty {
width: 200px;
height: 200px;
}
div {
border: 2px solid green;
}
<div></div>
<hr>
<div>
<p>some text</p></div>

According to www1:
"The float property can have one of the following values:
left - The element floats to the left of its container"
and also "In HTML, the container is the area enclosed by the beginning and ending tags. "(www2)
In the following code (code in 1):
.div1 {
float: left;
width: 100px;
height: 50px;
margin: 10px;
border: 3px solid #73AD21;
}
.div2 {
border: 1px solid red;
}
<body>
<h2>Without clear</h2>
<div class="div1">div1</div>
<div class="div2">div2 - Notice that div2 is after div1 in the HTML code. However, since div1 floats to the left, the text in div2 flows around div1.</div>
</body>
Questions are:
Is body element the container of div1?
If it is, div1 float to the
left. And I guess it ends the function of float. Why does the text
in div2 flow around div1?
So, in your example, my answers to your questions:
Yes
Think about all of the properties you're assigning to the div1 class - you've assigned a margin (thus displacing the text within div2), and are 'floating' that div to the left.
div tags don't natively have float: properties - in the absence of one, it behaves natively - keeping its position, taking up the full width of its container.
The screenshot below is meant to visualize what I'm trying to say above in #2
Oh, and the float: CSS directive isn't a function - but a style applied to an element on the visible DOM.
Personally and depending on what I'm trying to accomplish, I almost never use float in production if I can help it.
I am using stylus in my React project. I am using calc function to set height of some divs. But the calc is not not getting applied. On the client side when I inspect the element, I see the height attribute as calc but the element doesn't obey it. This is how I am setting height
.ht-full-70 {
height: calc(100% - 70px) !important;
}
When I inspect it, I can see the style there
But element is not taking this. It remains unaffected by this.
I think you need a wrap div around the element that you are trying to set a width for. This will make sure that the element has a set starting point for percentages if you give this wrap a height too. I demonstrate it in this snippet.
.ht-wrap {
padding-top:20px;
display;inline-block;
height:280px;
background-color:blue;
}
.ht-full-70 {
padding:6px;
display;inline-block;
height: calc(100% - 70px) !important;
background-color:red;
}
<div class="ht-wrap">
<div class="ht-full-70">
<p>Text.</p>
</div>
</div>
Because .ht-full-70's parent tag doesn't set height
You should set height of .ht-full-70's parent tag.
I am trying to create this effect by using HTML in UIWebView control of iOS. The goal is to create the effect of progress bar on the listing. So far I tried this but as you see, by adding a padding on diV makes everything messed up. How can I achieve similar effect? I have no issue of using table but seems that would be more difficult.
Thanks
Why not just use nested divs and give the inner Div a percentage width.
<div><div class="inner"></div></div>
And CSS:
div {
background-color: blue;
height: 30px;
}
.inner {
width: 50%;
background-color: skyblue;
}
Since divs are block level element they have a 100% width by default so you don't need to explicitly specify it for the outer div if that is sufficient.
Another possibility would be to use a background gradient and just move alter the background-position.
In the code you supplied you have this div:
<div style='position:absolute;left:0%; background-color: hsl(30,100%,59%);width:30%;z-index:10;'> </div>
Just add "top: 0px;" to it so that it becomes
<div style='position:absolute;left:0%; top: 0px; background-color: hsl(30,100%,59%);width:30%;z-index:10;'> </div>
And it will look correct.
Edit: And then give the LI elements position: relative to make it work with multiple elements. See http://jsfiddle.net/tFn78/9
Another version which is a bit cleaner: http://jsfiddle.net/v7zNn/ and adjusts to variable height of the title.
I have a div with two nested divs inside, the (float:left) one is the menu bar, and the right (float:right) should display whatever content the page has, it works fine when the window is at a maximum, but when i resize it the content is collapsed until it can no longer has any space, at which it is forced to be displayed BELOW the left menu bar, how can I make the width fixed so that the user may scroll when resized?
(css width didn't work, i alternated between floating the right content and not), here is the code:
<div style="width:100%">
<div style="float:left; background:#f5f5f5; border-right:1px solid black; height:170%; width:120px;"></div>
<div style="margin-right:2px;margin-top:15px; margin-bottom:5px; width:100%; border:1px solid #f5f5f5"></div>
</div>
I only need to have this working on Interner Explorer for now.
This should do it (container is the parent div containing that 2 divs):
.container {
width: 1024px;
display: block;
}
You may want to set a width on the containing div and set your overflow property
#containing_div {
width: 200px;
overflow: auto;
}
Also use the min-width property on the page if that makes sense, however that CSS property doesn't really work with IE6, this is usually what I do in that situation (supporting Firefox, IE7, IE6, etc)
#container {
min-width: 1000px;
_width: 1000px; /* This property is only read by IE6, which gives a fixed width */
}
Well, putting a width or min-width property is the way to go.
Now, without an example, or a link of the actual page, it's a bit tricky to answer.
Simply don't make the right div floating. Menu is already floating left of any other content. Just set a left-margin for the right div so the content in that div won't be wrapped around the floating div.
if the two divs are taking up 100% of the available width, could try to use percentage width and display: inline with a further div with a fixed min-width/width (boo IE) inside where required.
this is rather difficult without some HTML to go on
Your containing div should have a width wide enough to contain both inner div's
So if your two inner div's are 300px each and assuming you have no margin/padding on them then you should set the outer div to be 600px;
I'm a bit confused:
Fixed width means the width of a node will not change. Never.
You say you want to scroll when the screen gets too small for your content, so I think you mean the exact oposite of fixed width.
If my assumption is right, you could as mentioned before go for the percentual widths.
Watch out width the suggested "min-width" solution because it is not supported all that well.
<div id="container" style="width:100%">
<div id="primaryNav" style="float:left; width:150px; background-color: Orange">someNav</div>
<div id="content" style="margin-left: 10px; background-color: Red; overflow: auto;">

This should be pretty cross browser
Here's a question that's been haunting me for a year now. The root question is how do I set the size of an element relative to its parent so that it is inset by N pixels from every edge? Setting the width would be nice, but you don't know the width of the parent, and you want the elements to resize with the window. (You don't want to use percents because you need a specific number of pixels.)
Edit
I also need to prevent the content (or lack of content) from stretching or shrinking both elements. First answer I got was to use padding on the parent, which would work great. I want the parent to be exactly 25% wide, and exactly the same height as the browser client area, without the child being able to push it and get a scroll bar.
/Edit
I tried solving this problem using {top:Npx;left:Npx;bottom:Npx;right:Npx;} but it only works in certain browsers.
I could potentially write some javascript with jquery to fix all elements with every page resize, but I'm not real happy with that solution. (What if I want the top offset by 10px but the bottom only 5px? It gets complicated.)
What I'd like to know is either how to solve this in a cross-browser way, or some list of browsers which allow the easy CSS solution. Maybe someone out there has a trick that makes this easy.
The The CSS Box model might provide insight for you, but my guess is that you're not going to achieve pixel-perfect layout with CSS alone.
If I understand correctly, you want the parent to be 25% wide and exactly the height of the browser display area. Then you want the child to be 25% - 2n pixels wide and 100%-2n pixels in height with n pixels surrounding the child. No current CSS specification includes support these types of calculations (although IE5, IE6, and IE7 have non-standard support for CSS expressions and IE8 is dropping support for CSS expressions in IE8-standards mode).
You can force the parent to 100% of the browser area and 25% wide, but you cannot stretch the child's height to pixel perfection with this...
<style type="text/css">
html { height: 100%; }
body { font: normal 11px verdana; height: 100%; }
#one { background-color:gray; float:left; height:100%; padding:5px; width:25%; }
#two { height: 100%; background-color:pink;}
</style>
</head>
<body>
<div id="one">
<div id="two">
<p>content ... content ... content</p>
</div>
</div>
...but a horizontal scrollbar will appear. Also, if the content is squeezed, the parent background will not extend past 100%. This is perhaps the padding example you presented in the question itself.
You can achieve the illusion that you're seeking through images and additional divs, but CSS alone, I don't believe, can achieve pixel perfection with that height requirement in place.
If you are only concerned with horizontal spacing, then you can make all child block elements within a parent block element "inset" by a certain amount by giving the parent element padding. You can make a single child block element within a parent block element "inset" by giving the element margins. If you use the latter approach, you may need to set a border or slight padding on the parent element to prevent margin collapsing.
If you are concerned with vertical spacing as well, then you need to use positioning. The parent element needs to be positioned; if you don't want to move it anywhere, then use position: relative and don't bother setting top or left; it will remain where it is. Then you use absolute positioning on the child element, and set top, right, bottom and left relative to the edges of the parent element.
For example:
#outer {
width: 10em;
height: 10em;
background: red;
position: relative;
}
#inner {
background: white;
position: absolute;
top: 1em;
left: 1em;
right: 1em;
bottom: 1em;
}
If you want to avoid content from expanding the width of an element, then you should use the overflow property, for example, overflow: auto.
Simply apply some padding to the parent element, and no width on the child element. Assuming they're both display:block, that should work fine.
Or go the other way around: set the margin of the child-element.
Floatutorial is a great resource for stuff like this.
Try this:
.parent {padding:Npx; display:block;}
.child {width:100%; display:block;}
It should have an Npx space on all sides, stretching to fill the parent element.
EDIT:
Of course, on the parent, you could also use
{padding-top:Mpx; padding-bottom:Npx; padding-right:Xpx; padding-left:Ypx;}
