%%\titleformat{<command>}[<shape>]{<format>}{<label>}{<sep>}{<before-code>}[<after-code>]
%%
%%where [<shape>] and [<after-code>] are optional parameters, and:
%%
%%    <command> is the sectioning command to be redefined: \part, \chapter, \section, \subsection, \subsubsection, \paragraph or \subparagraph.
%%    <shape> is sectioning paragraph shape; possible values are: hang, block, display, runin, leftmargin, rightmargin, drop, wrap and frame.
%%    <format> is the format to be applied to the title, label, and text; for example \normalfont\Large\bfseries
%%    <label> specify sectioning label.
%%    <sep> is the horizontal separation between label and title body and it must be a length and not be empty.
%%    <before-code> is code preceding the title body.
%%    <after-code> is code following the title body.
%%
%%and
%%
%% \titlespacing{<command>}{<left>}{<before-sep>}{<after-sep>}
%%
%%where:
%%
%%    <left> increases the left margin.
%%    <before-sep> is the vertical space before the title.
%%    <after-sep> is the separation between title and non-sectioning text.
%%
%%The starred version of this command (\titlespacing*) kills the indentation of the paragraph following the title.

\textcolor{white}{{\large Regardez-sous la surface, plongez dans les profondeurs marines et découvrez les enjeux des communautés d'êtres-vivants. Des milieux les plus glacés de l'océan austral aux milieux les plus chaud des dorsales océaniques,  des communautés s'installent, des communautés survivent. Un écosystème se met en place dès l'origine de la vie. Face aux invasions virales les communautés océaniques se réinventent. Face au changement climatique, certaines espèces prolifèrent, attaquent et intoxiques. Parfois, la solution est dans une relationnelle fusionnelle, la symbiose où chaque individu apporte ses compétences. } }
