I'm noticing some significant differences in the appearance of my website when using Firefox and I can't seem to

This is my website

While the site looks almost perfect in Chrome, there are some display issues in Firefox. In Firefox, all text appears centered on the page rather than within the divs where it should be. Additionally, a filter problem causes every div to turn black, which is especially problematic since the site primarily consists of images.

The HTML Structure:

<div id="container">
        <div id="row">
            <div class="cell A1"><img class="spacer" src="spacer.png"><div id="text">MIKEY<br/><p>SPINDRIFT KIOSK</p>DIGITAL COLLAGE</div></div>
            <div class="cell A2"><img class="spacer" src="spacer.png"><div id="text">ERIC<br/><p>LIZ & RYAN HEMSWORTH</p>ALBUM DESIGN</div></div>
            <div class="cell A3"><img class="spacer" src="spacer.png"><div id="text">MIKEY<br/><p>EPHEMERA</p>DIGITAL COLLAGE</div></div>
            <div class="cell A4"><img class="spacer" src="spacer.png"><div id="text">ERIC<br/><p>REJJIE SNOW</p>SITE DESIGN</div></div>
            </div>

These are just one row, with three more rows following the same structure.

CSS: To simplify, I have provided the code for only one row here:

.A1, .A2, .A3, .A4 {
        position:relative;
        }

        .A1:before, .A2:before, .A3:before, .A4:before {
        content: "";
        position: absolute;
        width: 100%;
        height: 100%;
        top: 0px;
        left: 0px;
        transition: opacity .2s ease-in-out;
        -moz-transition: opacity .2s ease-in-out;
        -webkit-transition: -webkit-filter .2s ease-in-out;
        filter: url(filters.svg#grayscale); /* Firefox 3.5+ */
        filter: gray; /* IE6-9 */
        -webkit-filter: grayscale(90%) brightness(30%); /* Google Chrome, Safari 6+ & Opera 15+ */ 
        z-index: -1;
        }

        .A1:before {background-image:url('spindrift.jpg'); background-size:cover;}
        .A2:before {background-image:url('daynnite.jpg'); background-size:cover;}
        .A3:before {background-image:url('ephemera.jpg'); background-size:cover;}
        .A4:before {background-image:url('rejjiesnow.jpg'); background-size:cover;}


        .A1:hover:before, .A2:hover:before, .A3:hover:before, .A4:hover:before, {
        -webkit-filter:none;
        }

            /* text hover */
        div.cell:hover #text{

        -moz-transition: opacity .3s ease-in-out;
        -webkit-transition: opacity .3s ease-in-out;
        }

        font:12px ProximaNovaRegular, sans serif;
        text-decoration:none;
        }

        p {
        font:16px ProximaNovaBold, sans serif;

    .container{

        .row{

        width:700px;
        height:auto;
        transition: opacity .3s ease-in-out;
        -moz-transition: opacity .3s ease-in-out;
        -webkit-transition: opacity .3s ease-in-out;
        }

        html{
        margin:0;
        padding:0;
        height:100%;
        width:100%;
        }

        body{
        height:100%;
        width:100%;
        margin:0;
        padding:0;
        background-color:black;
        color:black;
        }

    /* hover */

div.cell:hover {
filter: none;
-webkit-filter: grayscale(0);
transition: opacity .3s ease-in-out;
-moz-transition: opacity .3s ease-in-out;
-webkit-transition: opacity .3s ease-in-out;
opacity:1.0;
}

I'm unsure what's causing these issues, and I apologize for the vague question. To provide more context, please review the source code on the actual site.

Answer №1

It is important to start your document with a doctype tag to specify the HTML version you want to use. Without it, the browser will default to Quirks mode, which may not display your content correctly.

Your HTML markup contains errors that are not compatible with the specified HTML version. For example, nesting <div> inside <a> elements is only allowed in HTML 5. If your doctype does not declare HTML 5, the browser may attempt to correct this by moving the div outside the a element.

You also have issues with nested elements being in the wrong order, such as:

<div>
  <a>
    <img>
    <div>
    </div>
  </div>
</a>

In this example, the closing tags for div and a are incorrectly ordered.

The stylesheet should be placed within the <head> tag, not outside of the HTML document completely.

Additionally, ensure that the <head> and <title> tags are included as required elements in your HTML document.

Addressing these issues will help you achieve consistent results across different browsers.

Answer №2

Eliminate from the #text

position:absolute

I have tested this on FF28 and it appears to be functioning correctly.

Please inform me if this aligns with your requirements.

Additionally, it seems that your background is not displaying in FF. You may want to consider adding all Vendor prefixes to your background-image property:

-webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;

Answer №3

Your website is currently in 'quirks mode' due to the lack of a doctype, which can result in inconsistencies across different browsers. To ensure uniformity and compatibility, it is essential for all new web pages to include a proper doctype declaration like this:

<!DOCTYPE html>

By including this declaration, you will switch all browsers into 'standards mode'.

However, transitioning to standards mode may cause some layout changes as your page was not initially designed with this in mind. It is still crucial to make this adjustment.

Furthermore, there are issues with your markup, particularly with placing script tags outside of the html element. The html element represents the document itself and should not be compromised in this way.

To identify and address all errors on your website, please use a validation tool such as W3C Validator. Currently, your site has 98 HTML errors that need attention.
