What are the HTML entities for up and down triangles?

I've found the outlined versions, but I want th开发者_如何学Ce solid up and down triangles.

Does anyone know these entities?

All named HTML entities are specified in chapter 24 of the HTML standard. The only thing missing from the page are rendered entities, but you can easily create your own copy with the additional information by applying a simple regexp:

s/<!ENTITY (\S+)/<!ENTITY \1 &\1;/

Not all entities are named. For many, you need to specify the Unicode code page, either in decimal (▲ ▲, ▼ ▼) or hex (▲ ▲, ▼ ▼).

A little but late, but you can use ▾ ▾, and ▴ ▴, to make both the up and down filled in triangles. I was looking for it myself and the alt codes didn't help so I decided to share this. This same thing works for both left and right as well.

I don't know if I've ever seen what you're looking for. Maybe a better way of doing it would be to create the arrows in Photoshop on a transparent background (.gif or .png format), and then load up the images.

Check that, you can do it through alt characters.

using the alt characaters on your computer keyboard is a big no no if you are working on a web page for many reasons. #1. encoding of the website, encoding of the database driving the website if any, the codepage of the computer view the website, the codepage your own pc's keyboard is set to.. all that are mostly factors you can not control. So some people will see wonky weird letter combos or sqiggle characters instead of what you intend. For webpages use the html codes for those characters when ever you can. or at least entity encode and make sure you have your code page defined in your html header of your site.. that way people will see what you intend them to.

now if you are doing this in word for a document that will be viewed in your own country you are probably safe. But for online things (site coding or data entry) you should avoid this like the plague.
