Can div really override table for everything on layouts? - html

Maybe there is already a question about this subject, but I couldn't find it.
My question is simple,
Can I use only divs on a page layout?
I got myself in trouble to create a div with corners for example.
A_____B______C
| |
D E F
| |
G_____H______I
take all letters as divs with some background, while letter E is where the content is placed, and it is dynamic, so it can get any height, while the width will be 100% for whole window(there is another div as the menu floating left of that div, but I didn't consider it here).
in table I did that really quick with no hack, but with divs I just couldn't.
I couldn't make the height of div D and F expand correctly with divs, the rest was ok
so,
1. can div really replace tables for layout?
2. can div replace tables without css compatibility-hacks?
(btw, that wasn't my only problem with div and css for layouts where table did it easily)

Your example is completely doable in basic CSS using absolute positioning inside relatively positioned element. Take a look at this:
http://www.ulmanen.fi/stuff/box.php
So, in answer to your question, divs really replace tables for layout.
And what goes for question number two; tables should be used where tables are needed: in tabular data. If you need to present something in a table, use a table. Just don't use them for layout.

Yes.
Sadly, no. Your example will almost certainly require some "hacking" to work in all browsers. Some things that were easy to do with layout tables are very, very complex to implement using pure CSS.
For your example, the following questions should provide you some pointers to work with.

Not really answering your question, but Yahoo has some nice grid CSS tools that really help with doing div-based layouts. These might be useful as a reference.

Yes, you can.

or, for the future (as it's not supported in IE 6 or 7), you can just use display: table to get <div> elements to lay out exactly like a table

can div really replace tables for layout?
Generally it's worth aiming for. But for everything? No. There are common table constructs which cannot be reproduced with CSS, particularly where you are mixing fixed-pixel, font-relative and viewport-relative measurements in one table. Complex liquid form layouts are the usual case for this.
In theory you could replace <table>, <tr> and <td> with divs styled as display: table-cell et al. However this won't work in IE, and is of questionable usefulness: you are still leaking the layout concerns into the markup just as much as if it were a table. (Plus you can't do spanned cols/rows like this.)
I got myself in trouble to create a div with corners for example.
You mean with image corners? That's really easy. But the trick is not to try to do it by positioning elements. Instead, use nested divs, each with its own background. For example:
<div id="foo"><div class="left"><div class="right">
Content.
</div></div></div>
#foo { background: url(mainbackground.gif); }
#foo .left { background: url(leftborder.gif) top left repeat-y; }
#foo .right { background: url(rightborder.gif) top right repeat-y; padding: 32px; }
That gives you a left and right border image laid over the main background. You can do the same three times to get a full table-like with 8 border images, or just nest divs nine deep. You can reduce the number of divs required from 3 to 2 if you can include the main background image in one of the border images (this may require very wide images if the element may grow large). You can use padding on some of the elements if you need the border images to be transparent (ie, the main background image isn't to be rendered on the edges).
In the future, this will become much easier and remove the need for so much nested markup, thanks to CSS3's proposed multiple backgrounds per element and border images.

You should make rows with the divs, as you would with tables.
Put abc in a div | let's call it div 1
Put def in a div | let's call it div 2
Put ghi in a div | let's call it div 3
Let e determine the height of div 2, and let 2 determine the heights of d and f. Using the proper position, such as position:relative, and display:table-cell you should be able to manage.
Not going to create the whole solution.

Elements in CSS Grid Column, top margin behaves as position top

Difficult to come up with a good title - by all means, change if you can.
Traditionally, a margin on an element can be used to move elements around a page relative to its previous elements. So, if I had a div as a column on my page I could shift elements vertically within that by setting their top-margin CSS property.
This is handy in dynamic pages where some elements might not exist according to given condition, eg, a very simple example here:
https://jsfiddle.net/jhartnoll/4s6pcLu0/1/
I have simply defined a column with a div element, positioned two other div elements and made one of them have a 2em vertical gap between it and its predecessor.
If you remove (or set Display:none) element #one then element #two is shifted up the column and positioned 2em from the top of the column, rather than 2em from element #one which is no longer there.
However, if I try to do a similar thing using a CSS grid, thus making the DOM tree simpler and more flexible, I run into a problem:
https://jsfiddle.net/jhartnoll/xvhycg0k/11/
In this case, the columns are set by the CSS grid so are sort of pseudo columns, but when I set my elements to have margin-top: 2em the margin is calculated from the top of the grid column, not relative to a predecessor element.
Therefore, if element #one is not present, #two simply remains 2em down from the top leaving a gap above...
This behaviour renders margin-top useless, because it is exactly interchangeable with top on relative positioned elements.
Is this a bug with CSS Grid, or am I using it wrong, or is there a way around this?
CSS Grid seems great, but I have run into several problems like this where dynamic content is concerned, if elements have potentially variable heights, or may not be there at all, the Grid leaves other elements floating in space, unable to shift up.
EDIT for clarity of the dynamic problem
Thanks for the comments so far. The problem is not with using the layout, I understand how to set up grids, and rows, define sizes, spaces, span etc, the problem is with dynamic content.
Supposing I have an extremely simple product page:
https://jsfiddle.net/jhartnoll/xvhycg0k/42/
Irrespective of the grid spacing, row/column size etc, the concept is simply that I have thrown in a "Price reduced by 10%" splash element above the product title.
Naturally, product pages would be using templates and therefore the HTML and CSS should be fixed and flexible enough to enable elements to be missing or present.
Not all product pages will display the 10% off deal, so on those pages, I would want the Product Title to shift up into the top element position.
This, as far as I can tell, cannot be achieved with grids.
Similarly, if there was a div which contained a product description and underneath it some product cross promotion or something, the description might be of variable length, so with the div as a column example in the my original question, the content would automatically expand the description grid and shift the cross promotion stuff down the page. Again, this can't be achieved with grids?
So, I was messing around with using a grid defining columns only and simply one row per page so that content could be stacked in columns similarly to the original div as a column example, but then I ran into this margin-top problem which, within a Grid is that margin-top is relative to the grid top, not to the elements above.
So I can't find a way of creating a dynamic website, using a template design which allows for conditional elements and variable element dimensions using Grid and without using Javascript to manipulate on page load.
In my mind, there should be an option for a row-shift property to allow elements to jump down a row if the content is too large, or jump up if there is nothing obstructing it... or something like that anyway!
Hey try the following code I guess it will help your requirement!
#column{display:grid;grid-row-gap: 10px;width:4em;height:auto;border:1px solid grey;}
#one{background:red;width:2em ; height:2em}
#two{background:blue;width:2em ; height:2em}
<div>
<div id="column">
<div id="one">
</div>
<div id="two">
</div>
</div>
</div>

How to make table column scrollable with multiple columns frozen in Angular 2?

I have a table that contains 3 columns that need always stay at the left side and column that contains grid where each grid element represents one hour in day, so I need that column to be scrollable. I tried many suggested solutions, but most of them are using position absolute, which is a bad joke, since when I use it I lose advantage of table, e.g. height of row changes, those absolute positioned don't follow. And the other problem is that table consists of few Angular 2 components, it's not just plain html, which makes it harder. Is there any better solution than using position absolute?
Well, in the end I just went with this solution:
Fix and Scrollable table structure using html div
It still uses absolute columns and so fixed widths and margins, but well I can live that as long as it works. About Angular component elements representing row of table, I just gave display: table-row to it and simply put td tags inside, so no longer need to use tr.
I made this approach. I't will work for vertical and horizontal directions.
https://plnkr.co/edit/MWFJuiWsUoo39xbCwAKI?p=preview
onScrollA($evt) {
this.divC.nativeElement.scrollLeft = evt.srcElement.scrollLeft;
}
Maybe try with position: sticky; But without code, it is hard to see where the problem is.

Alignment across table rows of divs with dynamic height (fluid layout) - CSS

I'm working on a mobile site, which has a fluid layout. On the main page, I have a table which contains a few products.
Each product has 3 divs: product-image, product-name and prices-container.
I can't seem to figure out how to align the prices-container div horizontally across the table-rows.
I'm thinking that there would be 2 approaches to this problem: either product-name always takes the height of the highest product-name across the table-row, either prices-container always sticks to the bottom of my product table-cell. Can't seem to figure out how to apply any.
Here's an illustration of the problem.
Left image shows my problem and right image shows how I would like it to be.
This wouldn't be a problem if product-name would have a fixed height, but due to the fact that this text is dynamic, I cannot know what height it will have. Might be one line of text, might be 10 lines.
I created a CodePen, where you can check my code and the problem >>here<< (I know it looks ugly, using background-colors to figure out faster what's happening).
I'm using Jade for my HTML and Stylus for my CSS.
Limitations:
- must be CSS & HTML only, I would prefer not using Javascript
- solution must be suitable for fluid layout (width is set with percentage)
- cannot use a fixed height of product-name, this being a dynamic text
Any ideas how to do this? Thank you! :)
add vertical-align:bottom; css style to .box1 class.
Similarly, add same style for .box4 css class.
Thanks,

HTML/CSS - 3 columns that resize

I am building a very simple page, powered by tumblr.
It has 3 columns of content in the main area. The content divs are all set to a width of 33% and floated left, most of the time this arranges itself as you would expect, but as you resize the window it seems to sometimes revert to 2 columns. Anyone know how to solve this?
The html is here: http://emilestest.tumblr.com
Try to set the .item css width to: 32%. The browser probably miscalculates width sometimes so you probably have a extra pixel or two, so the float overlaps to next line.
There is a Javascript action involved. Your article html elements gets the absolute position and some coordinates. Have a look over those scripts (or disable them, in order to use only CSS for positioning).
In your specific case, there are several solutions:
Place + size the divs with JavaScript and disable CSS layout
Use display: table
Use a table element
Disclaimer: For all those who cry out when they read table:
Using divisions to simulate a table for the display of tabular data is as much a design flaw as using tables to control graphic and page layout.

Is there a simple 3-column, pure CSS layout?

One that doesn't require the following:
Reliance on images (i.e. "faux columns")
Some kind of weirdness or "hack" put in specifically for IE
Requires IE to run in quirks mode
Doesn't have strangeness like one of the three DIVs overlapping the others (i.e. "holy grail")
Margins set to high negative numbers placing them well off the viewscreen (again "holy grail" layout)
I can't find a 3-column layout in CSS that doesn't rely on one of the above. And relying on one of the above seems to negate a lot of the advantage of using CSS over tables. I don't want to have to whip out Photoshop and resize an image every time I want to change the width of my left column. And I don't want to have to pull out the calculator to figure out how many pixels off the side of the screen my DIV has to be.
I should mention that I'm looking for an equal-height layout.
Anyone?
EDIT: I'm looking for a width of 100%, with the center column being liquid.
EDIT: I'm also hoping to specify the width of the left and right columns in pixels.
EDIT: Backgrounds can be transparent, but I would like a dividing line between the columns which runs all the way up and down.
There is no such thing as "simple" when you talk about CSS.
But there is a simple solution that is cross browser, degrades gracefully and is fully HTML and CSS compliant: use a table with three columns.
Reasoning: DIVs are not meant to have the same dynamic height. Therefore, CSS has no support for this. If you need a block element which makes sure that its children have the same height, then that's what tables are for.
[EDIT] Sorry to offend all you CSS fanatics out there but, frankly, when something is not designed to do something and you abuse it, and it doesn't work, please stop complaining, ok? A DIV is not a TABLE and can't be used as one without relying on hacks.
[EDIT2] As was said already in various places, the reason not to use tables for layout was that, in early times, tables were the only design element and that lead to HTML which had dozens of nested tables. That's bad. But that doesn't mean you must not use a single table to put everything in place and then rely on CSS to make the stuff inside look right.
A brain is like a parachute: It's nice to have but only useful when it's open.
You might be able adapt:
http://matthewjamestaylor.com/blog/perfect-3-column.htm
I agree with Robert. Due to browsers interpreting CSS rules and rendering the final page differently I doubt you'll find a perfect solution without being more flexible in your requirements.
You can achive this by using jS.
If you were to create 3 Divs one float left one flot right and the middle as margin left & right with a width to centre it.
Then with a bit of JS each div having their own ID you could calcultate their height set the 2 lowers ones to the highest value.
Pretty simple with Jquery.

This one can be used for a 3-column layout (and for various other layouts). Personally, I don't think it's a great idea to use divs for everything, but it's simple and well .. it works.
edit: For a 100% width layout http://www.alistapart.com/articles/fluidgrids/ may help, but I'm not sure if this kind of layout still qualifies as "simple".

divide page into three columns, same height?
<html>
<head>
<style type="text/css">
#col_wrapper{
height: 400px;
}
.col{
width: 33%;
float:left;
height: 100%;
}
</style>
</head>
<body>
<div id="col_wrapper">
<div class="col">
one
</div>
<div class="col">
two
</div>
<div class="col">
three
</div>
</div>
</body>
no quirks and pretty plain.
