I'm trying to put the colspan, valign and align in the following piece
<td style="background-color:#000333" colspan="4" valign="middle" align="center">
all inside the style="...", to have something like:
<td style="background-color:#000333;colspan:4;valign:'middle'; align:'center'>
Is there any way to do this?
You will be unable to achieve colpan results with CSS I stand corrected, you can in CSS3. But text-align:center will get and vertical-align:middle for vertical alignment.
With that said, please consider using proper CSS rather than stuffing things into the style tags, that will make your (and everybody else's) job much easier in the future. That is as simple as saying
<td class='myclass'>
and then inside your CSS file
td.myclass
{
text-align:center;
vertical-align:middle;
}
You cannot do that because there is no way in CSS to do the job of colspan (except in a special case where its value equals the total number of columns, and even then only using a proposed CSS extension that does not work consistently across modern browsers, not to mention old browsers).
I am trying to make a plugin for WordPress.
It works great, except when i load the default WordPress themes. e.g. "twentyeleven."
This theme has a DOCTYPE as shown below. And hence, no matter what I do, it always inserts this annoying GAP when i put an image in a table.
Please Help!
How do I get rid of this gap?
Below is some code. Anytime a table is placed in a situation in which the DOCTYPE is defined as it is here, then I get this gap.
The WordPress default themes seem to use this DOCTYPE declaration. So they BREAK my pretty plugins...
<!DOCTYPE html>
<body>
<table border="1" style="border-collapse: collapse;">
<tr>
<td width="100%">
<img border="0" src="http://goo.gl/PJdRU">
</td>
</tr>
</table>
</body>
</html>
All browsers render the above code as shown below. I just want to REMOVE the Gap! Thanks!
There are several solutions, but neither is perfect. I guess the easiest will be just change your img's style - in CSS (with td img { display: block } rule) or just an inline style, like this:
<img style="display:block" border="0" src="http://goo.gl/PJdRU">
Here's an article with explanations why you see what you see - and several possible ways of fixing it. ) And here's a working JSFiddle to play with.
I have a client form which includes HTML served up from an iframe - I can't edit it. The only thing I can do is apply CSS edits.
I'm trying to apply a simple adjustment which would stack the <td>s in the form so
1. What is your age?
becomes
1.
What is your age?
If you right click the first question and Inspect Element you'll see the rather interesting DOM structure I get to work with. This example it looks like this:
<div id="Age" class="questionlabel">
<table border="0" cellpadding="0" cellspacing="0">
<tbody>
<tr>
<td>
<span class="questionnumber_questionlabel">1. </span>
</td>
<td>
<label class="required">What is your age?</label>
</td>
</tr>
</tbody>
</table>
</div>
When I inspect that <td> and add a display:table-row; it completely ignores me. This is in Chrome - I can replicate this DOM and get the CSS to do what I want in jsfiddle so I'm thinking there is a reset somewhere I can't see. I even tried display:table-row !important; to no avail. I can apply border:2px solid blue; no problem. I can apply display:none; no problem.
Any ideas as to what is going on here that would prevent this simple CSS param from working?
To re-iterate the ONLY thing I can do is apply CSS - No JavaScript and no HTML edits. Basically I pass in a CSS file in the url to the iFrame. That's all I get. Thanks!
EDIT: I apologize I had to remove the link to the example form on the live site.
Edit - screenshots had to be removed, but the solution is still valid.
Added this code to form-css.css, using Firebug. Beginning or end, it did not matter:
table#form_table div.questionlabel td {display: table-row !important;}
.questionnumber_questionlabel {margin: inherit!important;}
(Note: I reset that margin as the old one (-10px) was causing unsightly overlap.)
In Visualforce, I'm using an <apex:dataTable> component as follows:
<apex:dataTable value="{!Qualifications}" var="qual" styleClass="cv_table" >
<!-- etc... -->
... and then I'm using CSS to style the table, via the class name. Trouble is, VisualForce renders HTML like this:
<table class="cv_table" id="j_id0:j_id26" border="0" cellpadding="0" cellspacing="0">
<!-- etc... -->
The class attribute is there as I wanted, but there's also cellpadding and cellspacing specified, that interfere with my CSS.
Is there a way to stop Visualforce from rendering the cellpadding and cellspacing attributes for an <apex:dataTable>?
Mentioned above, have you tried removing the attributes? Specify the id
<apex:dataTable id="myTable" value="{!Qualifications}"...
then
<script type="text/javascript">
document.getElementById("myTable").removeAttribute("cellpadding");
document.getElementById("myTable").removeAttribute("cellspacing")
</script>
What about providing your own values for these (same as in the CSS)? Ugly but would work.
Other than that - attribute removal / reapplying the class with JavaScript?
I don't think that even removal of SalesForce CSS (<apex:page ... showHeader="false">) will accomplish this task.
I don't know if you can suppress those attributes in Visualforce.
But if the question you're really asking is how do I not let those attributes affect my overall design, then I think CSS can help.
The CSS equivalent of cellpadding is 'padding', and the CSS equivalent of cellspacing is 'border-spacing'. The latter only works on elements of type TD as far as I know.
.cv_table TD {
border-spacing: 5px;
padding: 5px;
}
It looks like abandoning the <apex:dataTable> tag and using the more low-fi <apex:repeat> tag might be the only way to do this.
What CSS should I use to make a cell's border appear even if the cell is empty?
IE 7 specifically.
If I recall, the cell dosn't exist in some IE's unless it's filled with something...
If you can put a (non-breaking space) to fill the void, that will usually work. Or do you require a pure CSS solution?
Apparently, IE8 shows the cells by default, and you have to hide it with empty-cells:hide But it doesn't work at all in IE7 (which hides by default).
Another way of making sure there is data in all cells:
$(document).ready(function() {
$("td:empty").html(" ");
});
If you set the border-collapse property to collapse, IE7 will show empty cells. It also collapses the borders though so this might not be 100% what you want
td {
border: 1px solid red;
}
table {
border-collapse: collapse;
}
<html> <head> <title>Border-collapse Test</title> <style type="text/css"> td {
border: 1px solid red;
}
table {
border-collapse: collapse;
}
<table>
<tr>
<td></td>
<td>test</td>
<td>test</td>
</tr>
<tr>
<td>test</td>
<td></td>
<td>test</td>
</tr>
<tr>
<td>test</td>
<td></td>
<td>test</td>
</tr>
<tr>
<td>test</td>
<td></td>
<td />
</tr>
</table>
The question asked for a CSS solution, but on the off-chance an HTML solution will do, here is one:
Try adding these two attributes to the table element: frame="box" rules="all"
like this:
<table border="1" cellspacing="0" frame="box" rules="all">
I just found the following. It's standards compliant but it doesn't work in IE. sigh.
empty-cells: show
I happened across this question and haven't seen any answers that really addressed the issue.
The problem results because IE7 does not see any internal content for the cell; in programming terms the cell is resulting as a null and like most things, you cannot border a null or perform any action on it. The browser needs an element/object that has a layout, in order to apply a border/layout.
Even empty <div></div> or <span></span> do not contain content, thus there is nothing to render, resulting in that null case again.
However, you can trick the browser into thinking the cell has content, by giving the empty div/span layout properties. The easiest way is to apply the CSS style zoom:1.
<table>
<tr><td>Foo</td>
<td><span style="zoom:1;"></span></td></tr>
</table>
This workaround is better than using a , since it doesn't unnecessarily mess up screen readers, and isn't misrepresenting the value of the cell. In newer browser you can use the empty-cell:<show|hide> alternative.
Note: in lieu of Tomalak's comment, it should be understood that hasLayout has nothing to do with null, it was merely a comparison of how the browser interacts and renders hasLayout similarly to how a database or programming language interacts with nulls. It is a strech, but I thought it might be easier to understand for those programmers turned web designers.
Ideally, you shouldn't have any empty cells in a table. Either you have a table of data, and there's no data in that specific cell (which you should indicate with "-", or "n/a/", or something equally appropriate, or - if you must - , as suggested), or you have a cell that needs to span a column or row, or you're trying to achieve some layout with a table that you should be using CSS for.
Can we have a bit more detail?
This question's old, but still a top result in Google, so I'll add what I've found:
Simply adding border-collapse: collapse to the table style fixed this problem for me in IE7 (and didn't affect the way they're displayed in FF, Chrome, etc).
Best to avoid the extraneous code of adding an or other spacing element when you can fix with CSS.
I guess this can't be done with CSS;
You need to put a in every empty cell for the border to show in IE...
empty-cell only fixed Firefox (YES I really did have this issue in Firefox) IE 7 & 8 were still problematic..
This worked for me in both Firefox 3.6.x, IE 7 & 8, Chrome, and Safari:
==============================
table {
*border-collapse: collapse;}
.sampleTD {
empty-cells: show;}
==============================
Had to use the * to make sure the table style was only applied to the IE browser.
Try this if you can't use non-breakable space:
var tn = document.createTextNode('\ ');
yourContainer.appendChild(ta);
I create a div style that has the same font color as the background of your cell and write anything (usually a "-" "n/a" or "empty") to give the cell content. It shows up if you highlight the page, but when viewed normally looks how you want.
I use a mix of html and css to create cross browser table grids:
html
<table cellspacing="1" style="background-color:#000;" border="0">
css
td{background-color:#fff;}
I haven't seen any issues with any browsers so far.
"IE" isn't a useful term in this context anymore now that IE8 is out.
IE7 always does "empty-cells:show" (or so I'm told ... Vista).
IE8 in any of its "Quirks" or "IE7 Standards" modes always does "empty-cells:hide".
IE8 in "Standards" mode defaults to "empty-cells:show" and supports the attribute via CSS.
As far as I know, every other browser has correctly supported this for several years (I know it was added in Firefox 2).
I'm taking this from another website but:
.sampletable {
border-collapse: collapse;}
.sampleTD {
empty-cells: show;}
Use for the CSS for the table and TD element respectively.
