I need to build style info within hiccup in order to place an element at a location indicated by the variables "top" and "left". My code looks like so:
(html [:div {:style (str "top" top ";left" left)} "some text"])
This code is pretty ugly. It would be nicer if hiccup automatically rendered the "style" attribute using standard CSS style rules... Then I could write the following:
(html [:div {:style {:top top :left left}} "some text"])
Is there already a library that does this? Or, do I need to roll my own solution?
Thank you Clojurians for any pointers!
You could write a function that would do that, and it would even be slightly less typing than the map. For example:
(defn style [& info]
{:style (.trim (apply str (map #(let [[kwd val] %]
(str (name kwd) ":" val "; "))
(apply hash-map info))))})
Which would allow you to write it like this...
(html [:div (style :top top :left left) "some text"])
Sample output from the function...
user=> (style :top 32 :left 14)
{:style "top: 32; left: 14;"}
