Firefox

My CSS grid has the following stylesheet :

<span id="declaration" class="declaration" style="grid-template-columns: 80px 10px 150px; grid-template-rows: 10px 10px 20px;">
.declaration {
    display: grid;
    margin-top: 20px;
    grid-column-gap: 5px;
}

The leftmost element of the grid has the following stylesheet :

<input type="text" id="etiquette" class="etiquette" title="label" style="grid-column: 1 / auto; display: initial;">
.etiquette {
    grid-row: 1 / span 2;
    margin-left: 5px;
    margin-right: 10px;
}

I'm trying to get the ligatures for a webfont I created to show up in Chrome and Firefox and IE; they currently only appear in Safari and iOS.

I'm trying to get the ligatures to appear on a larger site, but for the sake of testing, I create a simple HTML page here: http://partyglamourshop.com/joomla/ligatures.html

1. I created the webfont using fontsquirrel and made sure to include the unicode characters that have the ligatures that I want to appear on the page. I double and triple checked that they are in the woff, eot and svg files.

Hello,
i have a problem with the css rule display: flex. Well to be honest, the problem is with the Mozilla FireFox browser. Every other browser displays the page as i intend it to display, but with firefox there´s a problem.
I have a container with the class of promo that holds tree colomns with the class of coluna.

The CSS is as folows:
.conteudo .promo {
max-width: 100%;
display:flex;
flex-flow:row wrap;
justify-content:center;
}
.conteudo .promo .coluna{
-moz-box-sizing:border-box;
-o-box-sizing:border-box;
box-sizing:border-box;
width: 30.3333%;
padding: 5px;

Hope you can help with this, since i can't get any decent support from the firefox extension developer[s].

My nivoslider slideshow on my index page shows us correctly in chrome, IE 10 and opera.
Only in Firefox it shows us up on the right side.
Here is my site: http://www.colombian-emerald-jewelry.com/

How can I fix this ?

I appreciate your help
