I understand that <frameset> and <frame> tag are becoming deprecated. Is there a way to emulate resizable frames? What I want is a narrow separator separating the area either horizontally or vertically, which is movable by the user so that when one side of it becomes smaller, the other side becomes larger, and vice versa. I do not want to fill in each frame with an html page like the conventional frame, but instead with some DOM materials.
I know that CSS3 has resize attribute, but that controls only the size of itself. I am not sure if this is to be used for the solution.
I don't particularly prefer using JavaScript, but I am not excluding the possibility of using it if necessary.
Do not use frameset, please. I don't think jQuery resize will help you much, either.
The best way to do this is by using a "splitter". There are several plugins for jquery that will do this in many different way and they all are actually quite simple.
I have previously used this one: http://methvin.com/splitter/
You can find a nice demo here: http://methvin.com/splitter/3psplitter.html
From my point of view jQuery Resizable or such js things is your solution. Go for it's demos.
In case of using jQuery you'll have extra possibilities:
Maximum / minimum size
Constrain resize area
Delay start
Snap to grid
Here is a sample code for jQuery Resizable default functionality:
<style>
#resizable {
width: 150px;
height: 150px;
display: block;
border: 1px solid gray;
text-align: center;
}
</style>
<script>
$(function() {
$("#resizable").resizable();
});
</script>
<div id="resizable">
<h3>Resizable</h3>
</div>

Janus Troelsen's solution above is great if you don't mind tables.
I also found this solution by SoonDead without tables, which worked great with Chrome and FF, but had to spend a nasty amount of time for IE8. It's on StackOverflow as "Emulate Frameset Separator Behavior"
I would look into Javascript and drag and drop support.
In fact, an emulated frameset could be just two divs and a handle between them which can be grabbed to resize. JQuery has samples to demonstrate how to resize an element: http://jqueryui.com/demos/resizable/ I don't think it would be very difficult to expand that concept to fit.
Then I would load the documents via AJAX, and this could probably replace frames completely.

I want to resize input date boxes of TelerikDateRangePicker component in Blazor in order to fit it better in my page. It looks to be a bit long and I want to resize it. This is the original size:
I tried adding
<style>
.k-floating-label-container {
width: 140px !important;
}
</style>
to the header of the page when running which made it as follows:
However, when I do the same in my CSS file and then run the application it goes back to the default. Any idea on this?
I have contacted them and they said: "To resize the inner inputs for the DateRangePicker you can use some custom CSS styles. To make cascading easier you can use the Class parameter that is available for the TelerikDateRangePicker. To better illustrate the concept, I have created a small sample that you can see from this REPL link, as well as quickly run it to see the rendered result."
I have a small image that i need to repeat along the x direction, a specific number of times.
The 'row' of images should be scrollable, and i want to avoid tables if possible.
Is this possible to do with Html + Css? The html code will be dynamic generated using PHP.
Any extra-ideas?
Thanks!
I wonder if ajax has the best looking solutions for you, but you haven't really explained your scenario too well, why are you repeating the same image and making it scrollable? That doesn't sound like valid functionality for anything. Are you trying to scale a background image or something? IF so, what's with the scroll bar???
Anyways here you go:
http://wowslider.com/rq/ajax-image-scroller/
Garry's answer is good. If you just want regular scrollbars, however, wrap the dynamic area (into which you will be loading your images) with a div (or canvas, probably works the same way), and add a class to it. Then you can target all of the images with CSS and have them float, which will line them up, regardless of how many you load dynamically. (Just don't forget to put a width on the container.)
It would look something like this (short-hand, but you get the idea):
div.image-container {
width: 400px;
overflow: scroll;
}
div.image-loader img {
float: left;
}
<div class="image-loader">
<img/>
<img/>
</div>
I've seen an effect on a few websites that gives you what are essentially vertical 'pages' which each fill the browser window. Examples:
http://www.bleed.no/
http://www.weworkonsunday.com/
The first is a good deal cleaner and more sophisticated.
I've been puzzling how to achieve this effect. It would be simple enough to do with page anchors etc. if height wasn't an issue, but filling the vertical of the window (as well as the width) is what's throwing me off.
Is there a straightforward method I'm missing? Or is all some complex java tomfoolery?
Many thanks for any help
Conceptually I would build a vertical page with stacked divs all with the same class that responds to the height of the window (and also responds when the browser is resized). Untested code using jQuery:
<div id="page1" class="page">content</div>
<div id="page2" class="page">content</div>
<div id="page3" class="page">content</div>
<script>
// set up onResize event handler
window.onresize = onResizeScreen;
// run onResize event handler once on load
$.(function() { onResizeScreen(); });
// onResize event handler
function onResizeScreen(event) {
$(".page").attr("height", screen.height);
}
// function to scroll to specific page
function gotoPage(pageNumber){
window.scroll(screen.height*pageNumber-1);
}
</script>
<style>
.page {
width: 100%;
}
</style>
You sound new to solving these kinds of problems. If you don't know what the above means check up on jQuery and handling JavaScript events.
This result does require some javascript expertise (in the way thats is implemented in your examples).
There is a jquery library that tries to simplify this process.
http://stephband.info/jparallax/
Even tho there are no really simple way to implement. Among the reasons the effect is very layout dependent and being a "new" way of doing websites... it will take some time until someone tackles the problem.
Here is another example of how to implement parallax in the way you described without teh help of the lib.
HOW-TO: http://net.tutsplus.com/tutorials/html-css-techniques/simple-parallax-scrolling-technique/

I have searched a lot for centering a div, both horizontally and vertically, this is the method given everywhere:
div {
position:fixed;
top:50%;
left:50%;
margin-left:(div width/2)
margin-top: (div height/2)
}
I just found a new solution to centering a div, both horizontally and vertically, by wrapping it inside a table. I've tested it in ie7 and above, plus other browsers.
Here is an example : http://jsbin.com/ocenok/2/
I was wondering that the first method is found everywhere on the internet, SO, etc. and requires beforehand knowledge of width and height, or is usually calculated via Javascript.
The table approach seems flawless, and requires neither javascript, nor fixed height/width.
Are there any drawbacks to the table approach ?
(I do not know the height/width of the div that I want to center.)
Update (To make my question clearer) :
I myself hate using tables for non-tabular/layout data.
I know that what I want can easily be achieved using Javascript.
I figured I can achieve this using display:table, killing IE7 support.
But what I'm trying to understand is, that when I can achieve this using a single <table> element, what are the drawbacks, if any.
Checking Answers here and on similar questions, no one has recommended this method, even though it uses all valid HTML elements and syntax and rules.
If everyone is recommending to use javascript to handle presentation, even though it is easily possible using CSS, it must have some drawbacks.
Code :
<table>
<tr>
<td>
<div>This is div that needs to be centered.</div>
</td>
</tr>
</table>
and then apply the following CSS
table {
width:100%;
height:100%;
position:fixed;
top:0;
left:0;
}
table td {
width : 100%;
text-align: center;
}
div {
width:100px;
height:100px;
background:pink;
margin: 0 auto;
}
see the below function and change as per your needs
function positionLightboxImage() {
var top = ($(window).height() - $('#lightbox').height()) / 2;
var left = ($(window).width() - $('#lightbox').width()) / 2;
console.log("The calculated position is:");
console.log(top,left);
$('#lightbox')
.css({
'top': top + $(document).scrollTop(),
'left': left
})
.fadeIn();
console.log('A jQuery selection:');
console.log($('#lightbox'));
}
Updated answer HTML and CSS:
HTML:
<div id="outer"><div id="inner"></div></div>
CSS:
#outer {
position: absolute;
top: 50%;
left: 0px;
width: 100%;
height: 1px;
overflow: visible;
background:red;
}
#inner {
width: 300px;
height: 200px;
margin-left: -150px; /*** width / 2 ***/
position: absolute;
top: -100px; /*** height / 2 ***/
left: 50%;
background:#ccc;
}
Even more updated using jquery and always remain center when you resize the window too : http://jsfiddle.net/3aZZW/3/

There are different reasons why you should not use tables. Some which have already been discussed here. I understand that you are only using one row and you will hopefully try to keep your promise to not add any rows but if you come to break that promise, some of the reasons below will show a lot more significance, like the rendering speed and the screen reader issue. That's exactly why they call somethings standard and some not. Standards take everything and every situation into account.
Rendering speed issue:
One of the biggest drawbacks of tables is the way they are rendered by browsers. The inside of the table must be loaded before the position and size of the table can be exactly determined. This may cause problems if you are going to have a lot of information in the table.
Validness and standards:
Using tables for non-tabular data means you are writing invalid X/HTML. Which may be fine for some. But I don't recommend. See here
SEO:
I didn't know this before I did a search on some other less heard issues with using tables.
Search engines love valid code, so by not using tables it helps with
Search Engine Optimization (SEO).
See here for more info on this
Problems for screen readers and Braille displays:
Tables can't be used easily in screen readers. Check this article.
If you must use a table for layout, remember that screen readers and
Braille displays read tables row-by-row across the columns. The TAB
order also goes through the table in this way. So make sure that your
table structure makes sense when reading from left to right,
row-by-row.
On the + side:
I hate to admit that if you honestly use just that one table with one row and one column and with a very small amount of data inside (which I would call a limitation) then the page would probably render faster than the time you use Javascript but the other issues remain.
Tables are only meant to be used for tabular data - not for layout purposes.
Using tables for your problem provides a quick and easy solution for you but it doesn't mean it's the best, or correct method.
Just because something takes a little bit more thought and effort doesn't mean it should be avoided.
Use tables for this at your peril - your immortal soul may pay a heavy psychic toll at some future date for your actions today :p
According to StatCounter, as of November 2012, IE7 accounts for only 0.87% of the usage share of desktop browsers. It's not clear how accurate that measure is; some countries are probably disproportionately weighted and the sample-set almost certainly doesn't exactly match your user demographics, whatever they are. But, how much would you really lose by leaving IE7 behind? Might as well go with display: table;
On the other hand, it drives me nuts that display: table; is necessary. This is the closest I can get to a workable alternative:
HTML
<div id="pg-centerer">
<div id="shifter">
<div id="item">content</div>
</div>
</div>
CSS
#pg-centerer {
position: absolute;
left: 50%;
top: 50%;
}
#shifter {
position: relative;
height: 40px; /** Must set the height here. **/
left: -50%;
}
#item {
position: relative;
top: -50%;
}
So far, I haven't figured out how to avoid setting the height of the div#shifter element. Here's a working demo. I've tested this on Mac 10.8.1 FF 18, Safari 6.0, Chrome 25.0.1362.0 canary, and iOS Safari 6.0.1.
There is not much of a problem till you have small data inside table. Tables are somewhat heavy for browsers and with more data coming in, they make your web page response slower in comparison.
The example you have shown is only for an example but in real world you will have data inside it. If its going to be large try choosing a different method. may be the flexbox model or box model that is going to be supported in all modern browsers very soon. See an example here. http://www.kirupa.com/html5/centering_vertically_horizontally.htm
If the data inside is going to be small, feel free to user your method.
Directing my words to the geek inside who care not about standards, or multi-channeling content served... there is really just one technical problem with tables that I can think of, if you have large content inside that cell, the browser will wait for all content to load to be able to calculate the width and height of the cell before rendering... so if that content is really large and has large images, it will not render gradually... and making it a fixed table, well, the trick above won't work.
I depends on what you're trying to achieve. If it's just one page with one thing centered, then its great.
But I see you have set the table position: fixed. Which means it will scroll with you and go on top of content below. The other thing is that, if that table really fills up, you wont be able to see whats at the bottom of that table, since the position is set to fixed.
It's a great solution to center a small piece of text, image or information.
But its a bad thing to use within a page with a lot of other content or a lot of content within the table.
Side note: Using javascript to achieve something simple like that, is stupid. It can be done without javascript using CSS only. What if you use javascript to center something, and a client without javascript visits? Lets not destroy the web by using javascript/jquery for all the simple things ;)
http://phrogz.net/css/WhyTablesAreBadForLayout.html
Basically, it's slightly longer load times (JavaScript is slower), bad for screen readers (test it with one like JAWS), and hard to redesign (really only hard if you happen to forget why the heck you put a table there, so make sure to leave yourself a comment :). What would be really nice (I'm talking to you, W3C!) is something like box-align: x y;. Then you could also do things like align: center center or align: center bottom;.
I have a two column layout, with a gray sidebar on the right. I need the sidebar's height to expand when the height of the left column is increased (due to content being dynamically expanded). I can make the sidebar fit a static page, but I cannot get it to increase in size with the rest of the page. Did some Googling, but couldn't find a work-around that worked for me.
Does anyone know how to do this?
This is a common problem when using DIVS for this type of layout.
If you google 'Faux column' you should get some answers.
eg. http://www.alistapart.com/articles/fauxcolumns/
This may be slightly off but if you use jQuery on your site you can perform a quick calculation and resize all DIVs sharing a similar class to the maximum height:
$('.elements').height(Math.max($('#div1').height(), $('#div2').height()));
I have been haunted by this problem for a while and I wrote an article about this issue: Done with faux columns. Here is what I argued:
JavaScript based solution for this
problem is not worse than any other
solution. In fact if you are using
JavaScript, you may save a few hours
of frustration of trying to get things
working. People will warn you against
this by saying “What will happen if
the user turned off JavaScript?“.
Believe me, if the user has turned off
JavaScript, most of the web is broken
for him anyway. Your sidebar does not
matter to him.
As cballou mentioned, the simplest way to do this thing is to use JQuery code:
$(".sidebar").height(Math.max($(".content").height(),$(".sidebar").height()));
I changed the background-color to the same color as my sidebar, on that specific page, although I do have backgrounds for all my sections rather than one overall background. But that might not work for everyone.
In my stylesheet,
.sidec
{
background-color:#123456;
}
In my HTML page,
<body class="sidec">
content....
</body>
I recently saw a quite creative solution to this problem using the CSS properties position:absolute and border.
Definitely worth checking out to see if it works for you.
Link: http://woorkup.com/2009/10/11/really-simple-css-trick-for-equal-height-columns/
I'm not sure if this will help, as I'm a newbie. However, when struggling with getting my sidebar to show the whole content when I doubled it's size I did the following. I was changing my height and width with no response until I changed the class. My class was listed SB frame SB width. So when I changed my class to read SB height SB width it fit to my content instead of the original frame size. I also tried SB max sb width with worked too, but it took out my footer menu bar (meaning it wouldn't show it anymore). I went back to SB height SB width, and all is well. That's super duper elementary for all of you I'm sure, but just in case there is another newbie reading this that doesn't understand much about html code like myself... I hope this helps =)
Happy Holidays Everyone!
hugs, tara
I'm guessing you want to apply certain effect to your layout such that it will require both columns to resize together. If you want to dynamically change the values of the height of the columns, I doubt it will work simply with css unless you implement some javascript to control the style.
As Dal suggested, do look at the link on faux columns. As the name suggests, the solution isn't much about modifying the columns height. Instead, it gives the "illusion" that both columns appear to be of the same height when in reality they are not -- and is with the use of tiles of background image.
The idea is there isn't a need to complicate the mark-up. Simple structure with a touch of "illusion" with images is a common practice in web design.

With the poor attitude towards new members on here I expect to be barracked for this answer, here goes.
I got around this problem by creating a background image 960px wide 1px high with the two colors I needed for the columns in their respective widths (780px and 180px). I then used this as the background image for my container repeated on the y axis and made the content and the right sidebar background-color: transparent.
.container {
width: 960px;
background-color: #FFFFFF;
margin: 0 auto;
background-image: url(../images/bgs/conbg.jpg);
background-repeat: repeat-y;
}
.sidebar1 {
float: right;
width: 180px;
height:auto;
background-color:transparent;
padding-bottom: 10px;
}
.content {
padding: 10px 0;
width: 780px;
background-color:transparent;
float: right;
}
I am sure that this method has its limitations but it works perfectly on all my pages.
It is possible that I have not explained this very well, if so, be nice about it will you please. I will endevour to expand on my method(which is probably already common knowledge).
