Indenting in Posts, and hiding site title

How can I indent paragraphs in my posts when I publish them?

And also, how can I show only my logo and site description, and not the “site title”? But I still want a place to type the site title so that my blog displays correctly when I post links of it to, say, facebook. I just don’t want it to be visible on my website.

here is what the code for it is in my header.php childtheme.

<?php if ( get_theme_mod('site_logo') && get_theme_mod('logo_style', 'hide-title') == 'hide-title' ) : //Show only logo ?>
					<a href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php echo esc_attr(get_bloginfo('name')); ?>"><img class="site-logo" src="<?php echo esc_url(get_theme_mod('site_logo')); ?>" alt="<?php echo esc_attr(get_bloginfo('')); ?>" /></a>

			<?php elseif ( get_theme_mod('logo_style', 'hide-title') == 'show-title' ) : //Show logo, site-title, site-description ?>
					<a href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php echo esc_attr(get_bloginfo('name')); ?>"><img class="site-logo hide-title" src="<?php echo esc_url(get_theme_mod('site_logo')); ?>" alt="<?php echo esc_attr(get_bloginfo('name')); ?>" /></a>
					<h1 class="site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a></h1>
					<h2 class="site-description"><?php bloginfo( 'description' ); ?></h2>	    

		        <?php else : //Show only site title and description ?>
					<h1 class="site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a></h1>
					<h2 class="site-description"><?php bloginfo( 'description' ); ?></h2>
		        <?php endif; ?>
				</div><!-- .site-branding -->
			</div>
		</div>

Thanks!
