I have something like this:
<div id="content" style="visibility: hidden;">
<!-- 500 lines of HTML --->
</div>
This div contain divs that are shown via Javascript. The problem is that it makes my site's height too big even if nothing is shown.
I know I could just add the divs to be generated in the Javascript file, but I wonder if there is a CSS solution, since I like to have the "skeleton" in the HTML instead of the Javascript.
style="display: none" in the css
You can use display:none; instead of visibility:hidden;.
If you want to make it visible again, simply change it to display:block;.

Is it possible to prevent the effect of ng-show on a specific child element.
Lets say I have the following html.
<div ng-show="showParent" class="parent">
<div class="childOne"></div> <!-- don't hide this -->
<div class="childTwo"></div>
</div>
Now what I would like to achieve is hiding everything except childOne. Actually hiding a parent, but one or some of its children?
No, you can't. The HTML standard prevents that. All children get hidden when the parent gets hidden, and AngularJS just adds things to HTML, it doesn't change it.
However, AngularJS allows one variable to control multiple elements, and can probably help us get the same affects you want. So let's go back to what you are really trying to accomplish. To do this, we're going to need some more details that you took out in this question to make the question smaller (and thank you for that). What about just hiding childTwo is not working for you? Are there other things in parent you need to hide? We can put those in seperate elements (div or span or something) and hide those with the same variable as we hide ChildTwo. Does parent have some formatting (say, a border or something) you need to hide? We can change what classes are on parent based on the same variable we use to hide the other elements to something that removes the border and any other styling, effectively making it not visible, although still technically present in the DOM.
ngShow relies on a CSS class (.ng-hide). You may be able to override that class with your own more specific selector for just the divs you want excluded from the directive.
<div class="parent" ng-show="showParent">
<div class="childOne nghide-override"></div>
<div class="childTwo"></div>
</div>
Source: https://docs.angularjs.org/api/ng/directive/ngShow
(I'm unable to test this right now, but I'll mock something up shortly and edit/remove this if it doesn't work.)
You could also just split the children out into divs and hide the second div:
<div class="parent">
<div class="shown children">
<div class="childOne"></div>
</div>
<div class="hidden children" ng-show="showParent">
<div class="childTwo"></div>
</div>
</div>
Use Jquery unwrap.
Include jquery in your application:
bower install jquery --save
Set on ready unwrap to specified div:
<script type="text/javascript">
$(document).ready(function() {
$(".childOne").unwrap();
});
</script>
In HTML, how do I prevent this "linebreak" when using the <div> tag?
Example:
<div class="menu"><br><br>menu</div>
<div class="apple"><br><br>apple</div>
Visual example:
How do I make it so that apple appears directly to the right of menu? I can't seem to do that successfully; apple always appears to be below menu
NOTE: Pretend that 'apple' is inside its own invincible maroon box.
When using <span> instead of <div>, you need to get rid of the line breaks (<br>).
If using inline CSS (which is the style attribute), you may want to add style = "float:left;" to the first div only. This way:
<div class="menu" style="float:left;"><br><br>menu</div>
<div class="apple"><br><br>apple</div>
It sounds like you have two block elements that you would like to display side by side?
Have you tried using the "display: inline-block;" property in your css yet?
You can change your CSS to include the following;
div.menu, div.apple {
float:left;
display:inline-block;
}
You might also need to set the width of each to less than 50%.
<div class="menu"><br><br>menu<span class="youtube"><br><br>youtube</div>
Suppose I have the following html:
<div style="width:200px;height:200px;overflow:scroll">
...
</div>
If the stuff in this div ends up overflowing, the most popular way to change the scrolling position of this item is to use jQuery.scrollTop(). However, I have a situation where I would like to set the initial scroll position of the div using the source HTML. Is there a way of doing this? All examples I see online for doing this end up using javascript.
One way I tried is to write a scrollTop property on the element, like so:
<div scrollTop=20 style="width:200px;height:200px;overflow:scroll">
...
</div>
However, this does not work. Surely, there must be a way to set the initial scrolling position of an overflowing item via HTML/CSS...
Here is a full version of this code that illustrates that it doesn't work- The vertical scrollbar remains at "0": http://jsfiddle.net/gueBZ/1/
Can anyone help me to make it work? Thanks so much for any pointers!
<div style="width:200px;height:200px;overflow:scroll">
<br><br><br><br><br><br><br><br><br><br><br><br><br><br>
<div id="hello">autoscroll here</div>
<br><br><br><br><br><br><br><br><br><br><br><br><br><br>
</div>
then open the page as
page.html#hello
this is the only thing you can do, with HTML only
I'm having problems targetting the DIVs on this test page I made at http://flexibletheme.tumblr.com/
In particular I have a div with an id of columns (div#columns), I can't get the background color to change.
Any ideas on how to get the background to render in div#columns?
Add overflow: hidden to #columns to clear the floats.
Another common way to clear floats is the clearfix class.
Take your pick of the two methods, but in general overflow: hidden is easier if it works for you.
In the source code on your page, you're missing a double-quote:
<div id=columns">
Try changing it to:
<div id="columns">
I've got some HTML:
<div id="thing">
<div id="contentheader">
<h3>Header</h3>
</div>
<div id="contentcontainer">
<div id="image">
<img alt="balt" src="imagesrc">
</div>
<div id="body">
<p>hegl gegl</p>
</div>
</div>
</div>
I need to push the h3 in 'contentheader' down alongside the image in 'contentcontainer' while having the body text sit alongside it. Everything is of variable width save the image.
Perhaps an image will demonstrate better:
As you can see, grey corresponds with 'thing', green with 'contentcontainer' and blue with 'contentheader'.
Editing the HTML would be a major hassle. I also can't make anything other than the image fixed-width. Is it possible to do it with just CSS? (It'd be awesome to be able to do it with floats and stuff but I don't know if it's doable)
I don't think you're going to find a perfect solution with CSS. You could use positioning but you would probably run into issues if you had a long title that ran more than one line.
If you're open to using javascript the following non-framework snippet would work.
// Add the header inside the container div just before the body
containerDiv = document.getElementById('contentcontainer');
headerDiv = document.getElementById('contentheader');
bodyDiv = document.getElementById('body');
containerDiv.insertBefore(headerDiv, bodyDiv);
You could recreate this code as a neater, one-liner using jQuery or another javascript framework.
Sure, heres the Css for a rudimentary setup:

Ask if you have any questions.
The problem here is the HTML structure, it's not been written really with your goal in mind (which is a bummer!)
If all you're after is pushing the H3 container 'contentheader' down in line with the rest of the stuff inside 'contentcontainer' you could set a negative top margin on 'contentcontainer' to pull it upwards, and then add a positive top margin to the elements in 'contentcontainer' which need to go down (in this case 'image') giving the impression that the h3 section actually sits in with the rest of the content. It's a bit of a hack but it might do the trick if you can't alter the HTML.
