[QUOTE=Jimbomcb;30836798]One large jpg. Is it simply just a case of drawing it each time I clear the screen for the next frame or am I an idiot.[/QUOTE]

You could use two canvas elements, one for the background and one for the foreground, then the foreground canvas would be the only one to update saving you having to draw a large amount of image data every frame.

You could also just use a normal image element.

[l095]

Wondering if anybody can help me with this, I find it easier to explain with these two images.

What is happening:

What I want to happen:
[IMG]http://i.imgur.com/yLzL3.jpg[/IMG]

How can I achieve this?

Sorry for the shitty image quality.

Showing us your code might help.

What's up with the crappy performance in chrome, full screen at 1920x1200 it's getting about 30fps, compared to full 60 in firefox?

<p>User 13</p>
</div><!--END ONLINE-->

css

.online {
    position: fixed;
    top: 2em;
    left: 42em;

This will later on have to work with an undefined amount of "Users" I just need them that after a certain height (ex. 230px) for it to keep going on the right.

first and foremost, you should be using a list elements, not paragraph elements

<ul id="online_users">
  <li>User 1</li>
  <li>User 2</li>
  <li>User 3</li>
  <li>User 4</li>
</ul>

I agree, I have fixed that and continued to play with the css stylesheet but I can't seem to find a way to solve this problem. Any help will be greatly appreciated.

With HTML5 does the video tag work in the same kind of way as the canvas?
So the code inside it only gets used if the browser doesnt support HTML5?

In other words, if I wanted to have a video that plays using HTML5 but I wanted to have a fallback to flash
would I do it like(in pseudo code):

<video tag>

/////////  flash code here

</video tag>

Why does firefox display elements in a different way than chrome?

[img]http://gabrielecirulli.com/p/20110702-164103.png[/img]

There's no way to make the two look the same. If I add 1px to the height the chrome one will break, if I subtract the firefox one will break. This happens every time. What should I do?

It's because Chrome has GPU acceleration for canvas turned off by default.

Yes that's how it works. Here is an example: [url]https://developer.mozilla.org/En/Using_audio_and_video_in_Firefox[/url] (scroll down to fallback options).

Could you not just check what browser the user has and then apply different CSS according?

I wouldn't really like to do that, honestly.

[QUOTE=TeratybeS;30847943]I wouldn't really like to do that, honestly.[/QUOTE]

Have you tried setting top and bottom padding to 0 and then line-height the same as height?

[TeratybeS]

[QUOTE=Skorpy;30849452]Have you tried setting top and bottom padding to 0 and then line-height the same as height?[/QUOTE]
Hmm, no, but I don't think that would work (not gonna try now since I went for another approach)

[jaybuz]

[QUOTE=TeratybeS;30849468]Hmm, no, but I don't think that would work (not gonna try now since I went for another approach)[/QUOTE]

Try using line-height.

[editline]2nd July 2011[/editline]

And if that doesn't work try display: inline-block.

[TheDecryptor]

Firefox ignores line-height on submit buttons (and on <input type="button">, but not <button>), so all that will do is affect Chrome.

Browsers don't handle this stuff well, I don't think there's actually a single standard behaviour over it.

What is the best way to save forum post usernames?
Should I save a user id and then when I'm retreving the posts get the username? Or should I save the username along with the post in the database? I guess the latest is fastest but have the least compibatility with other forum functions.
But I want your opinions on this, like will it increase/decrease load times and what not. Implenting it is no problem, just want to make sure I go a safe and hopefully fast road.

anyone wanna tell me how stupid it would be to make a database table without a primary key?

[deadeye5362]

[QUOTE=Ac!dL3ak;30881056]anyone wanna tell me how stupid it would be to make a database table without a primary key?[/QUOTE]

Very, database algorithms like MyISAM get their speed from indexes, and without an index, you are sacrificing every speed boost that algorithm gives you.

[pdkm931]

[QUOTE=Erp;30879648]store the userid with the post[/QUOTE]

Good. Just wanted to check to be 100% sure that it's the optimal thing todo.

[QUOTE=zzlawlzz;30879709]id userid topicid and the post

id, user_id, post(the content), time(CURRENT_TIMESTAMP), thread_id.

Then I'll just have to build more on it as time goes on.

[QUOTE=deadeye5362;30881719]Very, database algorithms like MyISAM get their speed from indexes, and without an index, you are sacrificing every speed boost that algorithm gives you.[/QUOTE]

And a good idea is using the id as a unique or?

Also, I can't get this to work.

Quick Question:

If i buy a domain name from one website, but the hosting from another, is this do-able? Basically i want to reserve a site name but not pay the monthly fees yet because i've not got the content. I want to use lithium hosting but as far as i can see they don't do domain registering.

Cheers

Yes, it is possible.

I currently have this, but I wonder how I can keep this design, that is the text going over the box, and still have a button clickable under it.
