First of all, there is a CSS file at:
/components/com_dtregister/main.css
This will allow you to modify the styling of most elements of DT Register.
Also, any text can be modified in the language file here:
/components/com_dtregister/language/english.dtregister.php
Search for the text you want to change, make your changes, save it and upload it back to your site.
Changing the language or CSS files will require using an FTP client or a component such as JoomlaXplorer or eXtplorer.
Regarding your event title, throughout the registration process the title using the styling (or lack thereof) of your own template
It uses the componentheading class just like almost all other components do.
If you are referring to your event titles as shown on the main list of events, these are links so they pull the link styling from your template as well. There is styling in the main.css file for the alternating background colors of this list... you could add CSS to modify the links of the event titles... something like this:
.eventListRow1 a:link {
font-size: 10px;
font-weight: bold;
color: #ffffff;
}
Style it as needed and be sure to do an entry for .eventListRow1 AND .eventListRow2. You could also make an entry for a:visited and a:hover to modify the styling on rollover. Do an online search for CSS and you\'ll find tons of tutorials if you need additional help as to what to use to get the look you want. Hope this helps.
