HTML - Xmp Deprecated

Am I right in this:

instead of <i>, use <em>

instead of <center>, use CSS

instead of <b>, use <strong>

This is what I do now because it works and the above codes are shorter than if one had to write it with inline CSS.

What else than these 3 tags can you recommend that I use instead of the old HTML tags??

I am trying to make my code more standards compliant and use the "strict" DTD. But when I try to validate using the W3C validator, there are a few things that I'm having trouble with.

Target: I was using <a href target="blank" ....> to open some external links in a new window, but this isn't allowed in HTML 4 strict or XHTML 1 strict. What is supposed to be the replacement? The only thing I could find on a web search was a javascript, which I know little about. Is that the only alternative? (Seems a bit silly if it is, as this must be a commonly used feature.)

Align: I used this to centre graphics, but this isn't allowed either. Are we supposed to set up different image classes in the CSS to allow centering, left, etc?

br: Use of the <br> tag is allowed in HTML 4 strict, but there seem to be some paces where it isn't allowed. Does anyone have a reference to the rules for this?

Thanks

When <b> and <i> aren't?

I mean, aren't they are all equal at a semantic level?
And considering as for better semantic syntax you should be using <strong> and <em>...

Just wondering - anyone else have thoughts?

Hi all, long time no post for me, good to see still a vibrant forum.

I have been helping a friend with their existing site they built with Weebly. Weebly uses the deprecated html <font> tag to set the size of text the user sets via the GUI. Ive found the font tag does not play nice with line-height, I.e. when line-height is set to a value other than "normal", the actual size of the font in the <font> tags does not figure in the line-height calculation and if the font tag has a large size set, you get major bleeding - i.e. the line-height is too small. At least in Opera Chrome FF.

I came up with a solution which seems to work but I thought this should be a known problem but could not find anything. Thought Id check see, may be there is a better fix, or I m missing something. Current solution is:

font[size="1"] { font-size:xx-small; line-height:100% }
font[size="2"] { font-size:small; line-height:100% }
font[size="3"] { font-size:medium; line-height:100% }
font[size="4"] { font-size:large; line-height:100% }
font[size="5"] { font-size:x-large; line-height:100% }
font[size="6"] { font-size:xx-large; line-height:100% }
font[size="7"] { font-size:40pt; line-height:100% }

Can you see any problem with this.

Cheers,

Sam.
