Remove line breaks and fix widget design

1. you could try and solve it with css:
add this to the end of style.css of your theme:
h5.uppercase p {display:inline;margin-left:10px;}

if that does not work, you could try and edit your widget code from:

<h5 class="uppercase light"><?php the_time('F j, Y'); ?> <?php the_excerpt(); ?> </h5>

to:

<h5 class="uppercase light"><?php the_time('F j, Y'); ?> <?php echo strip_tags(get_the_excerpt()); ?> </h5>

2.
in style.css – this style influences some of the ‘widgets’ formats, such as the line inbetween, and the padding:

#sidebar li ul li {
				margin:0 auto; padding:10px;
				height:auto;
				background:url(images/divider.gif) no-repeat bottom center;
			}

look into sidebar.php and see where the code for this particular ‘widget’ starts ( it is maybe a <li> maybe with a class=”widget”; …) and see if you can add another class to this widget – which you can then use to style it.

you could also copy the code of the whole sidebar into a http://wordpress.pastebin.com/ and post the link here, so someone may have a lok at it.

called through wordpress widget handlers thingie

you might find some related code in functions.php of your theme.

check the documentation:
http://codex.wordpress.org/Function_Reference/register_sidebars

particular this line:
'before_widget' => '<li id=\"%1$s\" class=\"widget %2$s\">',

if your code in functions.php does not have this (%2$s) which enters an additional class to the widget, try and add it.

call it on only ONE widget

wordpress does this for you.
see this copy from your rendered html from the browser:

<ul id="sidebar">
	<li class="widget widget_categoryposts\"><h2><a href="http://www.josefinfundin.com/?cat=3"><img src="http://.......
.	</li>
	</ul>

</li><li class="widget widget_twitter\"><div><h2><a class="twitterwidget twitterwidget-title" title="Twitter: fundin" href="http://twitter.com/fundin" target="_

important:
there is just one thing: the line i posted:
'before_widget' => '<li id=\"%1$s\" class=\"widget %2$s\">',

has to use without the backslashes \ – so please edit this in your functions.php (remove these backshlashes).

result:
from the snippets of your site, you can see that the first widget now has an additiional class ‘.widget_categoryposts’ – which you can use to style it differently from the twitter widget for nstance which got the class ‘.widget_twitter’
