Via css. Put this inside the `&lt;head&gt;` tag.

    &lt;style type=&quot;text/css&quot; media=&quot;screen&quot;&gt;
    
    table{
    border-collapse:collapse;
    border:1px solid #FF0000;

    table td{

    }
    &lt;/style&gt;



    &lt;table border=&quot;1&quot;&gt;&lt;/table&gt;

should do the trick.

For internal gridlines, use the tag: td
For external gridlines, use the tag: table

I am creating an object structure and I want all sub classes of the base to be forced to implement a method.

The only ways I could think of doing it were:

1. An abstract class - Would work but the base class has some useful helper functions that get used by some of the sub classes.

2. An interface - If applied to just the base class then the sub classes don&#39;t have to implement the function only the base class does.

Is this even possible?

N.B. This is a .NET 2 app.

Any way to determine file age of an image in a folder using PHP?

If so, please give me an example!

thanks

<p>how do I display the gridlines in a HTML table?  (am using IE6)</p>


I want to nest `span` and `a` tags. Should I 

1. Put `&lt;span&gt;` inside `&lt;a&gt;`
2. Put `&lt;a&gt;` inside `&lt;span&gt;`
3. It doesn&#39;t matter ? 



Span inside anchor or anchor inside span or doesn&#39;t matter?

Imagine I have the following HTML:

    &lt;div&gt;&lt;span&gt;&lt;b&gt;This is in bold&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;

I want to get the HTML for the div, including the div itself. Element.innerHTML only returns:

    &lt;span&gt;...&lt;/span&gt;

Any ideas? Thanks 


How to get the HTML for a DOM element in javascript

I have a project which requires printing an HTML table with many rows.

My problem is the way the table is printed over multiple page. It will sometimes cut a row in half, making it unreadable because one half is on the bleeding edge of a page and the remainder is printed on the top of the next page.

The only plausible solution I can think of is using stacked DIVs instead of a table and force page-breaks if needed.. but before going through the whole change I thought I could ask here before.

How do I clear the content of my IFRAME element, using javascript, without loading a blank page into it?
    
I can figure out to do this: `iframe_element.src = &quot;blank.html&quot;`, but there must be a better, instant, method.

Apparently, this is harder to find than I thought it would be. And it even is so simple...

Is there a function equivalent to PHP&#39;s [htmlspecialchars][1] built into JavaScript? I know it&#39;s fairly easy to implement that yourself, but using a built-in function, if available, is just nicer.

For those unfamiliar with PHP, htmlspecialchars translates stuff like &lt;code&gt;&amp;lt;htmltag/&amp;gt;&lt;/code&gt; into &lt;code&gt;&amp;amp;lt;htmltag/&amp;amp;gt;&lt;/code&gt;

I know that &lt;code&gt;escape()&lt;/code&gt; and &lt;code&gt;encodeURI()&lt;/code&gt; do not work this way.

What is the HtmlSpecialChars equivalent in JavaScript?

I&#39;m using the proprietry MS &#39;filter&#39; property to try and create a non ugly equivalent to css3 text-shadow and box-shadow;

I was actually doing really well until I hit this problem. It looks like when I apply a filter to a div inside another div which also has a filter the filter effects end up being combined on the child object.

I&#39;ve tried using filter:none; to do a reset but no joy. I&#39;ve also tried different variations on the syntax, ie &quot;-ms-filter: &#39;progid:...Glow()&#39;&quot;, &quot;filter: progid:...Glow()&quot;, &quot;filter: Glow()&quot;, etc..

How do I reset or override IE CSS filters?

I need to place a `div` (with `position:absolute;`) element in the center of my window. But I am having problems doing so, because the **width is unknown**.

I tried this. But it needs to be adjusted as the width is responsive.

    .center {
      left: 50%;
      bottom: 5px;
    }

How can I do it?





How can I center an absolutely positioned element in a div?

I am currently wondering what is the difference between the two. When I used both they seem to break the word if it is not fitting the container. But why did W3C made two ways to do it?
