How clean is this mustache template for a listing page?
By using excessive markup for presentational purposes, the template is the exact opposite of clean.

&lt;span&gt;&lt;i class="fa fa-phone"&gt;&lt;/i&gt;&lt;/span&gt;&lt;span&gt;{{{telefon}}}&lt;/span&gt;&lt;br /&gt;


vs.

&lt;span class="fa fa-phone"&gt;{{{telefon}}}&lt;/span&gt;
&lt;!-- span set to `display: block` with a `:before` pseudo element to contain the icon --&gt;


If you're not able to do this because of a library you're depending on, my recommendation is to find a better library.

By moving away from tables, you've committed a sin that's just as bad as using tables for layout:  you're using non-tabular markup for tabular data.  It is understandable that you don't want it to look like a table (either for aesthetic or responsive reasons), but tables don't have to look like tables any more than a list has to look like a list.

Go back to using tables and make adjustments to your CSS instead:

What the markup should end up looking similar to this:

&lt;table&gt;
    &lt;thead&gt;
        &lt;tr&gt;
            &lt;th&gt;Lab&lt;/th&gt;
            &lt;th&gt;Contact&lt;/th&gt;
            &lt;th&gt;Phone&lt;/th&gt;
            &lt;th&gt;Website&lt;/th&gt;
        &lt;/tr&gt;
    &lt;/thead&gt;

    &lt;tbody&gt;
        &lt;tr&gt;
            &lt;td class="name"&gt;ABC&lt;/td&gt;
            &lt;td class="contact"&gt;Johnny&lt;/td&gt;
            &lt;td class="phone"&gt;555-1234&lt;/td&gt;
            &lt;td class="url"&gt;http://abc.example.com/&lt;/td&gt;
        &lt;/tr&gt;

        &lt;tr&gt;
            &lt;td class="name"&gt;DEF&lt;/td&gt;
            &lt;td class="contact"&gt;Billy&lt;/td&gt;
            &lt;td class="phone"&gt;555-1234&lt;/td&gt;
            &lt;td class="url"&gt;http://def.example.com/&lt;/td&gt;
        &lt;/tr&gt;

        &lt;tr&gt;
            &lt;td class="name"&gt;GHI&lt;/td&gt;
            &lt;td class="contact"&gt;Dave&lt;/td&gt;
            &lt;td class="phone"&gt;555-1234&lt;/td&gt;
            &lt;td class="url"&gt;http://abc.example.com/&lt;/td&gt;
        &lt;/tr&gt;
    &lt;/tbody&gt;
&lt;/table&gt;


The CSS:

table, tbody, tr, td, th {
    display: block;
}

thead {
    display: none;
}

/* everything past here is optional */
tr + tr {
    margin-top: 1em;
}

.name {
    font-size: 1.2em;
    font-weight: bold;
}

.url {
    color: blue;
    text-decoration: underline;
}
