Css targets specific div tags on a large HTML page

Regarding my previous question here . If I use the HTML below as part of my webpage, where there are likely to be many other div tags, how can I target these individual divs in my CSS? The pattern that I think works best [This Answer] [2].

I added identification attributes to make divs more accessible in the large HTML DOM ... I don't know how else to make them more distinguishable. If there is a better way to do this, please let me know. The goal is to apply CSS design to about 6 div tag elements on the portal website with a lot of points. If there is a more general way that will be cool, so I can easily add additional sections and use this format in the future ... I can add a class attribute for each element to which I want to apply formatting, but I don't know the syntax.

What is a professional web designer for this?

<div id="projectName">
       Realtime Account Activiation
</div>

<div id="divAnnounce">
        Announcements
</div>

Identifiers are unique; they serve to identify a specific element of the page. So this is really the best way to achieve what you are looking for!

Style setting example:

#projectName {width:100%;}

Example of setting a jQuery event:

$("#projectName").click(function() { alert('Clicked'); });
