Re: link_to_next not working

Wrapping your links inside txp:link_to_prev / txp:link_to_next would prevent them outputting anything if there is no link, avoiding the need for your variable test, but … unfortunately it won’t put your desired class name on the link, only a wrapping tag.

Two options spring to mind. Use the regular tags and change your css:

<nav class="portfolio__meta__nav">
    <txp:link_to_prev><txp:prev_title /></txp:link_to_prev>
    <txp:link_to_next ><txp:next_title /></txp:link_to_next>
</nav>

and change in your css:

.portfolio__meta__prev {    --->   .portfolio__meta__nav a[rel="prev"] {
.portfolio__meta__next {    --->   .portfolio__meta__nav a[rel="next"] {

Or version 2, use txp:evaluate to test if a tag inside the container provides any output, e.g.

<nav class="portfolio__meta__nav"> 
    <txp:evaluate test="link_to_prev">
         <a href="<txp:link_to_prev />" title="<txp:prev_title />" class="portfolio__meta__prev"> <txp:prev_title /></a>
    </txp:evaluate>
    <txp:evaluate test="link_to_next">
        <a href="<txp:link_to_next />" title="<txp:next_title />" class="portfolio__meta__next"><txp:next_title /> </a>
    </txp:evaluate>
</nav>

Another tip – not relevant to the code snippets I posted here – but possibly a reason why you are getting gaps in your earlier code:

You can simplify your “if empty … else …”

<txp:if_variable name="myvar" value="">
<txp:else />
…
</txp:if_variable>

to this, so you have “if not empty …”:

<txp:if_variable name="myvar" value="" not>
…
</txp:if_variable>

PS: not means “the opposite of the if-expression you give it” (i.e. the else-case)

This is now working as desired!! So many thanks for all your insights.
Now on to the issue of outputting those 6 images along the bottom half!

PS I’ll try your other tips on my earlier code as well.
