I'm having a problem in the mobile version of my desktop. It's an edited versione of the classic theme for prestashop 1.7.6. Here's a link to the website.
In the footer, I have 2 consecutive divs, each one with its content. The first div has the block_myaccount_infos ID, the second one has the block-contact class.
The first div has a custom JS which should display the dropdown content, similar to the two sections before that. Since I noticed that the JS wasn't being executed, I used the chrome inspector tool, and I found out that the second div is overlapping the first one.
I tested adding a tag inbetween, which works, but it's not a valid solution to me since i need the two divs to be on the same line in the desktop version.
I see that you have
#media (max-width: 1025px)
#footer #block_myaccount_infos {
width: 34%;
display: inline-block;
float: left;
in your css. The issue is caused by that float: left;
If you alter or removed that and the <br> in your HTML, it should fix your issue. Hope that helps.
I am stuck with a problem : I want to make very simple "responsive design" for internal news site based on Sharepoint. The idea to make show only 1 block per row for small resolutions, and 2 blocks per row for larger resolutions.
I want to do it in this way :
https://www.dropbox.com/s/v2op6zgccujglcs/4.png
I tried to do it with Float:left , but it works bad in that situation:
https://www.dropbox.com/s/zh9wboi131of01l/3.png
Please, help me to find the best solution for this problem.
I see two potential questions you're asking:
1) "How do I make the content shift from three columns, to two columns using responsive design?"
and
2) "I'm having trouble with Content Choreography...", which is summed up in this article: http://trentwalton.com/2011/07/14/content-choreography/
I'll try to answer question 1, which is basically to use media queries to adjust your layout once it's under 1000px.
Here's an example you would put at the bottom of your stylesheet :
#media all and (max-width:999px) {
.yourDiv {
float: none;
width: 100%;
}
.yourOtherDiv {
float: none;
width: 100%;
}
}
This is the general idea anyway. You tell your floated divs to stop floating so they stack on top of eachother in a tunnel of content.
Question #2 is a little trickier to explain if that is what you were asking.
If you post your code, I would be happy to try and help more specifically.
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;.
Hi all and thanks in advance for your help.
I'm pretty new to the CSS, and I would like to have a good input to start building and learning the fastest way possible. I'm already doing some CSS tests myself. Right on the question.
this is the relative css code (I put it on pastebin because it's a bit long)
CSS CODE
As you can see in the code, the 2 tables showing up in the image, have a background and I had to set their size manually with
width:100px;
height:120px;
in the td.menuleft and td.menucenter classes.
1° Question
How do I make automatically resizing cells?
For example i want to say:
Make table tag wide 100% of the page width, then let me make classes for cell tables that are a certain percentage of the table width.
Example
Pic of my work, and how I want to make it like
This way it will be easy to make up tables into tags to automatically fill pages. I've seen something about positioning (relative, absolute) but I didn't managed to make it work.
2° question
What's the best way to structure a web page with css in general? It's ok to do like I said, a div, with tables inside and place every element in a table like manner?
Or can you give me any guide step to step on how to do a particular template?
Thanks guys.
when you want to learn how to make good and effective design that are also considered any worth by search engines, then don't use tables for layouts. tables are there for showing table data, not layout. Use instead divs and start reading about positions, displays, floats.
That is the way you want to go
If you set the tds to be a certain percentage width, they will be the percentage of the parent. so:
table {
width: 100px;
}
tr {
width: 100% /* Will be 100px */
}
td.quarter {
width: 25%; /* Will be 25px */
}
td.half {
width: 50%; /* Will be 50px */
}
And I agree with the previous poster, do NOT use tables for layouts. Not that you are doing that here. But for layouts stick to divs and such.
If you can read the Headings ... one's called JWT, the other Alela Diane.. how do I get "Alela Diane" to fill up the space between them ( no puns intended )
The CSS property for these div's is set to display: inline-block.
The HTML - >
<div id="shastra_display">
<div class="shastra_post">
There are multiple div's like this containing the Alela Diane's and JWT's etc.
</div>
</div>
The CSS - >
#shastra_display
{
width: 880px;
}
#shastra_display div
{
display: inline-block;
vertical-align: text-top;
}
.shastra_post
{
width: 270px;
background-color: light-grey;
}
Is it always going to be just two
columns? – thirtydot
It's two columns because the width of
the parent box allows only two to fit.
– Zach
So, the number of columns changes depending on the browser width.
That means you can't "cheat" and do it like this (as suggested by #Stefy):
http://jsbin.com/atimu4
Other than a fixed number of columns, CSS can't do it. See this answer for a comparision of the ideas:
CSS Floating Divs At Variable Heights
You will have to use JavaScript. There's already a convienient jQuery plugin: jQuery Masonry
Some interesting demos:
http://masonry.desandro.com/demos/animating-jquery.html
http://masonry.desandro.com/demos/adding-items.html
You should probably use a 2-column template in order to display the items properly.
