The Nuts

BBCode is a fashion to format text in forum posts. Information technology is in some ways like to HTML. It uses tags, which are piddling pieces of code enclosed in brackets, such as [b] to make bold text. For every tag, you demand a closing tag too. The closing tag is the same as the opening tag except that it has a / symbol at the front. For example, the tag [/b] is lawmaking for "end making the text bold." There is text between the opening and closing tags, that is the text that is modified past the tags.

For example, If you want to say "I dearest pizza" and want the give-and-take "love" to be in assuming, you lot would type

I [b]love[/b] pizza.

This would create, "I beloved pizza."

Below are some of the most unremarkably used BBCode tags around AoPS forums. For a comprehensive list of all BBCode tags, run across Listing of BBCode tags

The Buttons

This is a picture of what you see when yous create a topic or postal service a reply. On very small screens (such every bit a smartphone) these buttons volition not announced, so you will have to type the BBCode in manually.

The Bold Button

The push button is for bold tags. When yous click on information technology, your screen should look like this:

These are called bold tags. And so, you tin can type in whatever text you want:

When you submit it, information technology should look like this:

The Italics Button

The push is the italics button. When yous click on it, your screen should wait similar this:

Then you can blazon in your italicized message:

When you submit, it should look like this:

The Underline Push

The button is for underlining text. When you click on it, the symbols [u] and [/u] announced. So y'all tin type in whatever you want to be underlined:

When you submit it, it should wait like this:

Notation: you lot can also highlight text and then click the underline button.

The Quote Button

The button is for quoting text. You can write an anonymous quote, or quote a specific user or person. When you lot click on it, you get [quote] and [/quote]. And so type in the quote:

When yous hit submit, it looks like this:

Or, alternatively, you can say who quoted information technology:

And yous become this:

Y'all can also quote a post past clicking this push in the forum.

Yous will be taken to a reply page that looks like this:

The Size Button

The button with the 3 T's is for decision-making the font size. You can click on either "Too Small", "Small", "Medium", "Large", or "Too Big" depending on what size you want. After you click on 1 of them, you should get something like [size=75] and [/size].

The Hide Button

The button embeds text in a little interactive clicky. This is useful if you want your text only visible if the reader wants to meet it. For example, if you are answering a math problem, y'all tin hibernate the text so that y'all don't give abroad the answer to someone who doesn't want to know it.

Commencement by clicking the hide push button. You should get [hibernate] and [/hide]. Then put in your text:

When you submit, y'all get this:

If you click on the words "Subconscious Text", y'all go this:

Or yous tin can characterization your hidden text. Starting time, write in the code of the hidden text something like:

[hide=answer]Because 6x=y, and y is half dozen, then x must be 1.[/hide]

And then submit, you become:

The Lawmaking Button

The button is for posting code that you don't want to be rendered, ie LaTeX or BBCode. When you click on it, your screen should display:

[code][/code]

Type in your lawmaking:

[code]$10+nine=21$[/code]

And it should display:

Code submitted.JPEG

Notice that the LaTeX lawmaking is non rendered; that is, it does not bear witness up as $10+9=21$ .

If you desire a specific colour of lawmaking do [ code language ][/ code language ] such as [js][/js].

Another way for posting stuff that y'all don't want to be rendered, is the [verbatim][/verbatim] tags (non implemented on the top BBCode bar in the forums). There will be no grey box that there is when using [code][/code], and it will non automatically placed on it's own line.

The Image Button

The push is for embedding images in posts. If you accept this image:

And yous want it to prove up like this:

You lot use [img] tags. Click on the button and your screen should show:

[img][/img]

Now insert the link to the image. Make certain it is a direct link.

[img]http://artofproblemsolving.com/assets/images/logo-ludicrous.gif[/img]

When you submit, you should get the image!

The URL Push

The push is for parsing and naming URLs. If you click information technology, your screen should look like this:

[url][/url]

[url]http://www.aops.com/[/url]

When yous submit it, it should be parsed, like this:

http://www.aops.com/

Alternatively, if you want a link that goes somewhere but is not actually named the URL, exercise this:

[url=http://world wide web.aops.com/] Click here.[/url]

Yous get

Other Tags

There are other things yous can do with BBCode that do not have buttons in the AoPS community.

Unordered List

An unordered list is a simple bullet point listing. To use it, you simply use the [list] tag. Earlier each new list item, type [*]. The [*] tag is for a list item. You don't demand a closing tag for the [*] tag. For example, typing

            [listing]
            [*] pizza
            [*] pasta
            [*] rice
            [*] cereal

[/list]

creates:

pizza
pasta
rice
cereal

Ordered List

The BBcode for the following uses the [listing] tag. To tell you want a numbered listing, type [list=1]. For instance, typing,

            Elevation x most important people of all fourth dimension:
            [listing=ane]
            [*]GMAAS
            [*]Gauss
            [*]Hilbert
            [*]Leibniz
            [*]Cantor
            [*]Rusczyk
            [*]Patrick
            [*]Newton
            [*]Washington
            [*]Edison

[/listing]

creates

Acme x near important people of all time:

GMAAS

Gauss

Hilbert

Leibniz

Cantor

Rusczyk

Patrick

Newton

Washington

Edison

Alternatively, if yous want to brand a lettered list, start with [list=A] or [list=a]. For a roman numeral list, use [list=i] or [list=I].

Python Tags

If y'all are taking an AoPS programming with a Python class, y'all may need to post some Python code in the grade forum. To exercise this you utilise the [python] tags. These tags are like the [code] tags except that they prove the python code in colors. For example, typing

[python]

            print("howdy"+" earth")
            print("Hello, world!")
            [/python]

Yields

Python tags.PNG

If you lot want to have a Python renderer in a post in a forum, you tin use [pywindow] tags. For example, typing

[pywindow]

            print("Hello World!")

[/pywindow]

yields a code box that tin can be run and edited.

AoPS Font

Main article: AoPS font

Say y'all desire to blazon the Y symbol on a forum postal service. You lot can use the [aops][/aops] tags to create symbols similar this. For instance, typing

[aops]Y[/aops]

makes the Y symbol. For a guide to how to type other symbols, meet the AoPS font page.

Lines

If you wish to have a line that spans the unabridged width of the folio, y'all tin can utilise the [dominion] tag. For example, try typing

[dominion]

in The Test Forum. Should you not wish to use BBCode, you can employ 5 or more dashes instead.

Strike Through

The Strike Through tag looks like this:

Content:

Issue:

This is how to strikethrough.

Math

The Math tag looks like this:

Content:

Result:

Tip Tag

The tip tag is basically a hide tag, except it displays the embedded text when you hover over it. To use information technology, use [tip]This is the text![/tip], and supervene upon the text inside the tip with whatever you lot want. When yous submit you become this:

When you hover:

You can name tip tags with this code: [tip=Tip Title]content[/tip]
