Leveraging Alt Codes for dropdown menus in website navigation

I am currently using Alt Codes "▼" (Alt+31) for my navigation drop down and styling it with the following CSS.

ul>li.drop_down>a:before
{
content: "▼"
}

Is there a chance that this approach may cause issues, such as the character not displaying correctly in different operating systems or user agents? Would it be more reliable to use a background image instead?

My document is encoded in UTF-8 without BOM, with New Doc Format set to Unix and EOL set to Unix Format. I'm not sure if this information is relevant, though.

Answer №2

When dealing with characters like ▼, it is necessary to incorporate Unicode. Specifically for ▼, the code is \25bc.

For example:

ul > li.drop_down > a::before
{
    content: "\25bc";
}

It's important to mention that I used ::before, which is technically accurate. However, some versions of Internet Explorer might require you to use :before (although most browsers will still recognize it even though it's not standard). It's advisable to opt for :before, but ::before is the correct format.
