阅读更多关于 why is different from in XHTML?

Here's the complete source of an HTML page: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head></head> <body> one<br> two<br /> three<br></br> four </body> </html> Can anyone explain why an extra blank line appears between the "three" and the "four" when I view the page in IE8 or chrome? I thought standards were supposed to make all browsers look the same and as far as I can see this page conforms to the XHTML transitional standard Because the XHTML spec HTML Compatability Guidelines specify that br must should

Will deprecated elements be removed from future browsers?

阅读更多关于 Will deprecated elements be removed from future browsers?

What are cons to using deprecated elements if I don't care about validation and I use that DTD which supports them? Will deprecated elements will not be rendered by future browsers? Some online WYSIWYG editors (which we use in CMS) still give output in deprecated elements. Must I invest the time to change the output for a client? alt text http://easycaptures.com/fs/uploaded/241/3445655293.jpg Should we avoid deprecated elements at any cost? Currently all mainstream browsers show all deprecated elements. I just wanted to know the disadvantages of using deprecated elements to give to a non

Is it necessary to use H2 after h1

阅读更多关于 Is it necessary to use H2 after h1

Is it mandatory to use H2 after h1 if text is too small then can we use h4 after h1 . and is it accessible ? Toon Krijthe Technically you can use any combination of those. Semantically, it's wise to use the common order. And if the font size is too small, use CSS to change that. With the tags h1 - h6 you give a semantic meaning to a title. Where h1 is for the top level, h2 for a subdivision of h1 , h3 for a subdivision of h2 etc. You can change the appearance by setting CSS rules, which is great because now you can separate content from layout. You should always structure the document

Get HTML page <input> values and names using regex on PHP

阅读更多关于 Get HTML page values and names using regex on PHP

Ok, so as the title says, I have an HTML page that I fetch using libcurl (cURL inside PHP). That page has one <form> that I need to extract the <input> names and values, and I would like to do that using Regex. I'm making it using Regex because I think that's the easier way. If you think I shouldn't use regex, but something like xpath, say how. I don't know if you can understand what I'm trying to say, so feel free to ask. Here's the PHP code (complete): <?php /***** DISABLED BY NETWORK TRAFFIC REASONS... USING LOCAL CACHE $curl = curl_init(); $url = 'https://secure.optimus.pt/Particulares

<br> instead of <br/> in Visual Studio

阅读更多关于 instead of in Visual Studio

I use Visual Studio for teaching HTML. We use HTML 4.01 Transitional. Visual Studio defaults to XHTML 1.0, and I need to solve one problem with a typical difference among these two HTML standards: Whenever we enter <br> or <hr> , it is automagically changed to <br /> or <hr /> respectively. This is great for XHTML, but unwanted when working in HTML 4.01 mode. So how to turn off this automagical feature? We use mainly Visual Studio 2010, and sometimes also 2012 and 2008. (I know how to easily switch validation to HTMl 4.01 mode, but it still puts slashes to each <br> , <hr> etc.) Tools ->

问题 Eric meyer reset css is suggesting "tables still need 'cellspacing="0"' in the markup".
