Result:
This html code will work in: journal entries, group blogs and news articles. It won't work in notes, comments and artist's comments. It used to work in artist's comments, but for some reason, it doesn't any more.
Also, it's good to know: you can replace "center" with "right" ("left" would be useless since it's default.)

Font size - headings

Headings:Since you can't actually change the font size with normal font size html codes, you'll need to use headings. There are 6 headings types:
<h1>Example text</h1>
<h2>Example text</h2>
<h3>Example text</h3>
<h4>Example text</h4>
<h5>Example text</h5>
<h6>Example text</h6>

Result:

Example text

This code will work in (premium) journals, news articles, artist's comments and special boxes on user's profile. It will not work in comments.


Code: Used for defining computer code, but deviants just use it to change their font. <code>Insert text here</code>

Result: Example text
This html code will work pretty much everywhere, I think. I don't use it that often so I'm not sure, but considering the popularity of it, I think it works everywhere.

Links and photos

Including links to pages: <a href="insert url here">text that will be clickable</a>

Result: Here's a link to deviantART
This html code will work in: journal entries, group blogs, comments, artist's comments, news articles, but will not work in group notes.

Including photos: <a href="Insert link to the page where the photo is originally coming from"><img src="Insert link to photo"></a>
This html code will work in: Premium journal entries, Super group blogs, custom boxes.

Using big thumbs: <a href="Insert link address here"><img src="Insert Image URL here" width="Insert the desired width of the photo"></a>
This html code will work in: journal entries (for premium members only), Super group blogs and custom boxes.

To copy a link address, you need to go to the page of the photo you want to link and copy the address in the address bar of your browser. To copy image URL, you need to right click on the photo itself and select Copy image location if you use Firefox or something that implies that you're copying the location of the photo if you're using other browsers. The maximum size of a dA thumbnail is 150×150 which is rather small. Using 300 or 400 or even 500 pixels won't ruin your profile page if you're planning to use this in a journal, but bigger sizes will. The photos might even be cropped, depending on the size of your monitor and the size of the thumb.

Description pop-up:You can also include little pop-up text to your links by using this code:
<acronym title="popup text"><a href="insert url here">text that will be clickable</a></acronym>

Result: deviantART

Combining codes

You can also combine as many codes as you want. Let's say that the letter A is a start code and /A is the end code, and B is a different code that ends with /B, the same thing goes for C - /C and D - /D. The correct closing order goes like this: A B C D insert text here /D/C/B/A.
For example; here's a subscripted text that's bold, underlined, strike, italic, centerd and contains a link:


My code for this was:
<div align="center">_{<b><i><u><strike>This won't be easy to read, but you get the point. <a href="[link]">Here's a link to dA again.</a></strike></u></i></b>}</div>

I just wanted to show you all how ridiculously long and confusing this looks but it's really, really easy so don't be afraid of it.

Special characters

Here is the link to the special characters that you will probably use rarely. On the other hand, if you're ever planing to create a plz account or if you need to demonstrate html, these are the most common ones that you'll use:

Less-than sign: &lt;
Result: <

More-than sign: &gt;
Result: >

Colon &#58;
Result: :

Thumbs and username and icon tags

This isn't really html, but you'd be surprised how many people doesn't know how this works.

Usernames: :devusername:, e.g. :devshaplz:
Result: ~Shaplz

User icons: :iconusername: (that's how the plz accounts work), e.g. :iconshaplz:
Result:

You can also use these for linking groups.

Thumbnails:Including thumbnails is very easy because all you need to do is copy the code located on the right side of each deviation. It's under "Share" part of the deviations, below groups and above "Details" and "Statistics".
There is a "Thumb" box with the code that usually looks something like this :thumb208669995:
Result:

Remember

It's very important to close your tags with "</>" because the rest of the text will have the same effect like the one you wanted to point out.

Also, always hit "preview" button before you post a comment/journal entry/etc. no matter how sure you are you got it right.

If a deviant gets carried away with <sub> or <sup> tags, remember to


Remember that nobody knows all the tags by heart so don't be afraid to fave this article and visit whenever you need.

If you ever need some help with html, remember that Google is your friend.

If you know some other html codes that can be used on dA, feel free to share them. I never said I knew everything about this, I'm just here to share my knowledge.
