Do I need font-size:0? - css

In a previous question I got some excellent answers for placing 3 boxes in a row:
Can I place boxes three in each row, equally spaced and glued to container on left and right?
There is a nagging problem there. For the solution to work I have to put font-size:0 on the container. Which means I have to specify absolute values for fonts in the boxes.
Not really what I always want. Can I avoid that font-size:0?
Here is a new fiddle: http://jsfiddle.net/lborgman/BUYZ3/2/

Yes, you can avoid it by not leaving any whitespace in the markup between those elements..
One way to do that is to use html comments between the elements (in order to keep the code formatting you want)
<div id="container"><!--
--><div>one</div><!--
--><div></div><!--
--><div>three</div><!--
--><div>four</div><!--
--><div>five</div><!--
--></div>

The other is to just remove the whitespace
<div id="container"><div>one</div><div></div><div>three</div><div>four</div><div>five</div></div>

For this specific example you could also (more appropriate really..) float the elements..
float:left;

Cannot center text in HTML/CSS

The problem is (which you can see in the pictures below) that the "doner", "Wallet", and "Amount" aren't centered on the page.
I've tried changing the margin and padding and moving divs around and etc, but nothing seems to be working and I don't understand what is wrong or how to fix it. (it is hard to see in the code snippet because it's not full screen so I'm just going to give a link to the HTML here)
The only issue I can find is when I inspect element on google chrome. When I hover my mouse over <div class="container"> (the one underneath div class="learn-more">) It shows that the div container is wider on the right side, but I can't find why!
Thanks for the help! If you need any clarification please ask, I couldn't find anything to fix my problem online so I came here.
Here's a picture of what I mean as well:
The essential problem with your code is the markup. You're using the Bootstrap & putting some div directly inside the container & then another container inside this div. See what I mean:
Here are the first three rules from the 3rd Bootstrap documentation you should follow when building your HTML:
Rows must be placed within a .container (fixed-width) or
.container-fluid (full-width) for proper alignment and padding.
Use rows to create horizontal groups of columns.
Content should be placed within columns, and only columns may be
immediate children of rows.
So, my suggestion is to revise your HTML layout and use the Bootstrap as it intended instead of applying some hacks.
Start from rearranging containers in the way that the content would be put inside columns and all of the wrappers would be outside of the containers or inside the columns.
put your content that you want to center in a div like
<div class="box">your content...</div>
in your css file just add this :
.box{
display:inline-block;
position:relative;
left:50%;
transform:translateX(-50%);
}
you can also use a float left for your 3 titles and set the same witdh and height for the three with text-center proprety

How many times - or where - should I use a "container" class on css in Twitter Bootstrap?

But I am not really sure whether the idea is that I put one <div class="container"> around my whole page, or whether I should nest them. I think I see both in various examples.
Anywhere you want a div that is centered with a width of 940px. It is also used in the navbar to position elements. There are no hard and fast rules.
If it was only meant to be used once they would have given it an id instead of a class
I've been trying to figure out the same thing -- I think the idea is that .container is intended to be a fixed width div -- 940px in the default css -- whereas .container-fluid is, well, fluid. At least that's what I've sussed from looking at the css and the (sparse) documentation.

Float divs with variable heights (arrange)

I'm having a simple problem concerning the arrangement of floating divs with variables heights.
The goal:
The result:
I just have div containers with css float: left; and no height defined. The first red circle indicated that my technique fails, although the second one proves me wrong by showing it IS working. Unfortunately, the last (not on screenshots) just starts floating after the height of the previous one (so there's a whole empty space on the left).
How should i solve this?
Thanks!
I don't think that this is doable a 100% with "just" css, but jquery-masonry should do the trick [ http://desandro.com/resources/jquery-masonry/ ]. Well, but i hope somebody proofs me wrong :)
You have two columns. Then code it accordingly:
<div class="column">
contents of first column
</div>
<div class="column">
contents of second column
</div>
(you set float:left on the column DIVs)

One question about background overlay

<div>
<div>
<div></div>
</div>
</div>
It seems to me that the inner background will overwrite the outer one,why is it designed like this?
The backgrounds will nest...
Think of pieces of paper..., when you stack them, the first and largest is shown, if the size of the first is made smaller than the ones behind it, the ones behind it take up the space.
Transparency works with this same principle.
using the z-index property may give you more control over how elements overlap; however, it is only recommended as a last option if you are using an absolute-positioned layout. otherwise, stick with native HTML semantics and look up best practices on positioning elements.

Using Divs to display table-like data

I want to display data like the following:
Title Subject Summary Date
So my HTML looks like:
<div class="title"></div>
<div class="subject"></div>
<div class="summary"></div>
<div class="date"></div>
The problem is, all the text doesn't appear on a single line. I tried adding display="block" but that doesn't seem to work.
What am I doing wrong here?
Important: In this instance I dont want to use a table element but stick with div tags.
It looks like you're wanting to display a table, right? So go ahead and use the <table> tag.
I would use the following markup:
<table>
<tr>
<th>Title</th>
<th>Subject</th>
<th>Summary</th>
<th>Date</th>
</tr>
<!-- Data rows -->
</table>
One other thing to keep in mind with all of these div and list based layouts, even the ones that specify fixed widths, is that if you have a bit of text that is wider than the width (say, a url), the layout will break. The nice thing about tables for tabular data is that they actually have the notion of a column, which no other html construct has.
Even if this site has some things, like the front page, that are implemented with divs, I would argue that tabular data (such as votes, responses, title, etc) SHOULD be in a table. People that push divs tend to do it for semantic markup. You are pursuing the opposite of this.
I don't mean to sound patronizing; if I do, I've misunderstood you and I'm sorry.
Most people frown upon tables because people use them for the wrong reason. Often, people use huge tables to position things in their website. This is what divs should be used for. Not tables!
However, if you want to display tabular data, such as a list of football teams, wins, losses, and ties, you should most definitely use tables. It's almost unheard of (although not impossible) to use divs for this.
Just remember, if it's for displaying data, you can definitely use a table!
If there's a legitimate reason to not use a table then you could give each div a width and then float it. i.e.
div.title {
width: 150 px;
float: left;
}
Is there a reason to not use tables? If you're displaying tabular data, it's best to use tables - that's what they're designed for.
To answer your question, the best way is probably to assign a fixed width to each element, and set float:left. You'll need to have either a dummy element at the end that has clear:both, or you'll have to put clear:both on the first element in each row. This method is still not fool-proof, if the contents of one cell forces the div to be wider, it will not resize the whole column, only that cell. You maybe can avoid the resizing by using overflow:auto or overflow:hidden, but this won't work like regular tables at all.
or indeed this, which is very literally using tables for tabular data:
https://stackoverflow.com/badges
Just to illustrate the remarks of the previous answers urging you to use table instead of div for tabular data:
CSS Table gallery is a great way to display beautiful tables in many many different visual styles.
Sorry, but, I'm going to tell you to use tables. Because this is tabular data.
Perhaps you could tell us why you don't want to use tables?
It appears to me, and I'm sure to a lot of other people, that you're confused about the "don't use tables" idea. It's not "don't use tables", it's "don't use tables to do page layout".
What you're doing here is laying out tabular data, so of course it should be in a table.
In case you're unclear about the idea "tabular data", I define it like this: bits of data whose meaning isn't clear from the data alone, it has to be determined by looking at a header.
Say you have a train or bus timetable. It will be a huge block of times. What does any particular time mean? You can't tell from looking at the time itself, but refer to the row or column headings and you'll see it's the time it departs from a certain station.
You've got strings of text. Are they the title, the summary, or the date? People will tell that from checking the column headings. So it's a table.
The CSS property float is what you're looking for, if you want to stack div's horizontally.
Here's a good tutorial on floats: http://css.maxdesign.com.au/floatutorial/
display:block garauntees that the elements will not appear on the same line. Floating for layout is abuse just like tables for layout is abuse (but for the time being, it's necessary abuse). The only way to garauntee that they all appear on the same line is to use a table tag. That, or display:inline, and use only (Non-Breaking Space) between your elements and words, instead of a normal space. The will help you prevent word wrapping.
But yea, if there's not a legitimate reason for avoiding tables, use tables for tabular data. That's what they're for.
In the age of CSS frameworks, I really don't see a point of drifting away from table tag completely. While it is now possible to do display: table-* for whatever element you like, but table is still a preferred tag to format data in tabular form (not forgetting it is more semantically correct). Just pick one of the popular CSS framework to make tabular data looks nice instead of hacking the presentation of <div> tags to achieve whatever it is not designed to do.
display: block
will certainly not work, try
display: inline
or float everything to the left then position them accordingly
but if you have tabular data, then it is the best to markup in <table> tag
some reference: from sitepoint
You'll need to make sure that all your "cells" float either left or right (depending on their internal ordering), and they also need a fix width.
Also, make sure that their "row" has a fixed width which is equal to the sum of the cell widths + margin + padding.
Lastly make sure there is a fixed width on the "table" level div, which is the sum of the row width + margin + padding.
But if you want to show tabular data you really should use a table, some browsers (more common with previous generation) handle floats, padding and margin differently (remember the famous IE 6 bug which doubled the margin?).
There's been plenty of other questions on here about when to use and when not to use tables which may help explain when and where to uses divs and tables.
Using this code :
<div class="title">MyTitle</div><div class="subject">MySubject</div><div class="Summary">MySummary</div>
You have 2 solutions (adapt css selectors to you case):
1 - Use inline blocks
div
{
display: inline;
}
This will result in putting the blocks on the same line but remove the control you can have over their sizes.
2 - Use float
div
{
width: 15%; /* size of each column : adapt */
float: left; /* this make the block float at the left of the next one */
}
div.last_element /* last_element must be a class of the last div of your line */
{
clear: right; /* prevent your the next line to jump on the previous one */
}
The float property is very useful for CSS positioning : http://www.w3schools.com/css/pr_class_float.asp
The reason the questions page on stack overflow can use DIVs is because the vote/answers counter is a fixed width.
Tabular data can also be represented as nested lists - i.e. lists of lists:
<ul>
<li>
heading 1
<ul>
<li>row 1 data</li>
<li>row 2 data</li>
<ul>
</li>
<li>
heading 2
<ul>
<li>row 1 data</li>
<li>row 2 data</li>
<ul>
</li>
</ul>
Which you can layout like a table and is also semantically correct(ish).
For the text to appear on a single line you would have to use display="inline"
Moreover, you should really use lists to achieve this effect
<ul class="headers">
<li>Title</li>
<li>Subject</li>
<li>Summary</li>
<li>Date</li>
</ul>
The style would look like this:
.headers{padding:0; margin:0}
.headers li{display:inline; padding:0 10px} /The padding would control the space on the sides of the text in the header/
I asked a similar question a while ago Calendar in HTML and everyone told me to use tables too. If you have made an igoogle home page, just yoink their code.
I made a system of columns and sections within the columns for a page. Notice with google you can't have an infinite number of columns and that offends our sensibilities as object people. Here's some of my findings:
You need to know the width of the columns
You need to know the number of columns
You need to know the width of the space the columns inhabit.
You need to ensure whitespace doesn't overflow
I made a calendar with DIV tags because it is impossible to get XSL to validate without hard coding a maximum number of weeks in the month, which is very offensive.
The biggest problem is every box has to be the same height, if you want any information to be associated with a field in your table with div tags you're going to have to make sure the whitespace:scroll or whitespace:hidden is in your CSS.
Preface: I'm a little confused by the responses so far, as doing columns using DIVs and CSS is pretty well documented, but it doesn't look like any of the responses so far covered the way it's normally done. What you need is four separate DIVS, each one with a greater "left:" attribute. You add your data for each column into the corresponding DIV (column).
Here's a website that should help you. They have many examples of doing columns with CSS/DIV tags:
http://www.dynamicdrive.com/style/layouts/
All you have to do is extrapolate from their 2-column examples to your 4-column needs.
You should use spans with:
display:inline-block
This will allow you to set a width for each of elements while still keeping them on the same line.
See here, specifically this section.
Now, to appease the downvoters - of course tabular data should be in a table. But he very specifically does NOT WANT a table. The above is the answer to HIS QUESTION!!!
First display:block should be display:inline-block , Although you might have figured it out already.
Second you can also use display:table , display:table-cell , display:table-row and other properties.
Although these are not as good as using table.
