change the color of active links category

I wish the link of the category when clicked will change color, that include a: active. My templates is old comes from 12leaves put the link of the template where there is an online demo to not put your link on my site.
http://demo.zen-cart-themes.com/furniture/
I would be really grateful if someone helps me.

Unfortunately, most store-bought templates are nowhere near compatible with Zen Cart. So... they take to creating MANY stylesheets to try to cover up for their code changes. You will need to find out which of the stylesheets is controlling a particular "a" tag. Then, you can look at that stylesheet for an "a:active" call and try changing that.
If you use firefox and firebug, you can do this on the fly.

hello, using firebug but does not work a: active style sheet is this

**I post this but it seems to work
**

#vert_nav-cat li a:active {
   color: #A52A2A;
}

have you noticed that the template seems to be for 1.3.9b? Have you checked with the creator to see if the template is really 1.5.4 compatible? I know they claim it works with 1.5.x but, there are some big differences in just the 1.5 series.
Also, they claim that any color you choose will cause "Necessary elements change color automatically".
You can always post something for us to look at by using the yoursiteDOTcom method. That hides the site from the SEs till you're ready for them to look.

It works well with 1:54, ok place link horibalandDOTcom

Been 41 years since I was first stationed at Aviano, Italy. Lovely place. On the bucket list for get back there.:yes:
How's about a specific page we can talk about? Or, are you talking about the categories in the left sidebox?

We can talk you remember that I do not speak English and I translate everything with a translator must have a little patience when I read

Ciao! Proviamo questo . Il prolem è che non trovo il foglio di stile che lei ha citato in uso sul tuo sito. Mi può dare il nome del foglio di stile che hai postato sul forum ?

Voila
includes/templates/mobishop_blue/css/stylesheet_vert_categories_menu.css
stylesheet_vert_categories_menu.css

E ' tarda notte per voi . Possiamo continuare domani, se vi piace .

Thank you that we can

ps
after 20H00 Paris now if that's all right

Ora capisco che cosa si vuole , credo . Si dovrà creare il codice contro un foglio di stile per evidenziare quale categoria viene utilizzato dal cliente. Il foglio di stile non sa che "li" si sta guardando . Si sa solo di cambiare il suo colore se attivo . C'è un collegamento per un possibile risposta a .... https://www.google.com/url?sa=t&rct=...pkEDTSOcju0mCQ

Buona Notte

Buona sera

Here I am, you and the left sidebar categories I want the active link.

I have not been able to find anything that will highlight the category box in the left-hand column while the category is displayed. Marking the "li" as active only lasts until the category page is displayed.

Hopefully, someone with a little more knowledge can help us out.

I think you would need some code that recognizes which category is being accessed and change the background color for that category's link in the menu.

Ok thank you, we hope that someone will help me.

I understand which file to change, but I did not understand how to do hihih

I took a look at the site and category is highlighted, unless I misunderstood your request.

IT
Ho dato un'occhiata al sito e le categorie sono evidenziate, a meno che non abbia mal interpretato la richiesta.

Keneso thanks, I solved the case.

Keneso thanks, I solved it by editing tpl_categories.php.
