2) words are too close to thumbnail in my articles
3) when you open an article in larisagoal.gr the photo is at top of article and big (you can check it online) in mine is is still thumbnail
thank you in advance

We will need to see your site send us login so we could access it (use "Report To Moderator")

did you received my report to moderator? its the first time so i dont know if i did it right

1. At bottom of template_css.css define font looks for css entry:

.item > H2 > a{
font-size:...
color:...
....
}

add !important flag to property value if not applied first time when you save, like

font-size:20px!important;

2. add this:

.item IMG{
margin:10px;
}

change 10 if not enough

3. Add css definition for IMG for details page:

.item-pagemypagestyle IMG{
width:90%;
height:auto;
margin:0 auto;
}

thank you for your help
about my questions:
1) "in my site (messazzero photo) the headline is black and underlined, how can i make it like the 2nd photo (larisagoal photo)?" now headline is red but the same font type
2) "words are too close to thumbnail in my articles" problem solved
3) "when you open an article in larisagoal.gr the photo is at top of article and big (you can check it online) in mine is is still thumbnail" the guy in larisagoal just puts the photo and thumbnail is genarated at blog view and when you open the article the phot is large on top of article
thank you in advance
