How can I make my most recent post larger than the rest?

any advice will be greatly appreciated

Depends on which section you want to be bigger. Essentially, in your index.php file, you just need to add something like:

<?php if(!isset($firstPost): ?>class="first-post"<?php $firstPost = 1; endif; ?>

You can put that in your <div class="entry"> for bigger text, or in your <h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2> for a bigger title. Is that what you’re looking for

sorry, i’m a complete noob, but what do you mean “You can put that in your <div class=”entry”>”

because I do want to make the text and title bigger.

thanks so much for the help, i truly appreciate it

Similer twiter nice ??

Open up your index.php file, find the part that says <div class="entry"> and change it to <div class="entry<?php if(!isset($firstPost): ?> first-post<?php $firstPost = 1; endif; ?>">

In your style.css, you’ll need to add something like:

.post .first-post {
  font-size: 2em;
}

If you don’t know basic HTML or CSS, you’re going to have a lot of difficulty styling your theme though, I hate to say it. Best to hire someone to do it for you, if anything. Good luck.
