Inserting HTML element it's ok but I don't have it CSS control within RSD?
<ul class="myclass">
<li>
<img src="image1.jpg" />
</li>
<li>
<img src="image2.jpg" />
</li>
<li>
<img src="image3.jpg" />
</li>
<li>
<img src="image4.jpg" />
</li>
</ul>

Can you apply a background image to the li?

background yes and that's not what I want

I know I can add thru jQuery prepend ('Links for image'); method

it's little complicated after giving away the final production and for one whom is not really code savvy
Even
<div class="class" data-src="img2.jpg">
<img src="thumb2.jpg" />
</div>
is not possible.
the only method so far is add custom HTML element and inline styling but then that does not serve the purpose.

I have got to build with HTML editor that's weak point of RSD so far for me:(

I'm sure CC will put more options in place as they work on building the app.
Adding a little with the HTML Editor is still easier then hand coding the entire site.
Did you make it a suggestion?

One of the things that has worked well for me is I include a "styles" page with every project. No pages link to it. It's sole purpose is to include the styles for particular items that are added via an html element or elements added later in HTML Editor. Here's how I do it.

Add a styles page to your project. It should have the same layout structure as the other pages.
Add an image and add all the styling that you would use in the <li>.
Once you export the project, add the images to the list.
You might have to copy some css to your custom.css with a slightly different name depending on the css code generated by RSD, but it works well.

I have not made suggestion on this because I am sure CC staff surely will read this topic. and yeah lets hope they will implement it very soon as it helps building mage slide show much easier within RSD.

Thanks for suggestion Brian , For now I add as HTML element and build it's own custom css .

Brian, could you create a small sample site to show us with this styles page, I don't follow your explanation above.

I'm with Inger.

I'd like to see an example of this as well.
