Hello There,
Thanks for writing in!
1.) The size of the thumbnail can be increased by using this code:
.blog .x-main .hentry>.entry-featured,
.search .x-main .hentry>.entry-featured,
.archive .x-main .hentry>.entry-featured {
width: 40%;
}
.blog .x-main .hentry.has-post-thumbnail>.entry-wrap,
.search .x-main .hentry.has-post-thumbnail>.entry-wrap,
.archive .x-main .hentry.has-post-thumbnail>.entry-wrap {
width: 60%;
}
Feel free to change the width and make sure that the total width will not exceed 100%.
2.) To descrease the font size of the title and excerpts, you can make use of this code:
.blog .x-main .hentry .entry-title,
.search .x-main .hentry .entry-title,
.archive .x-main .hentry .entry-title {
font-size: 24px;
}
.blog .x-main .hentry .entry-content.excerpt,
.search .x-main .hentry .entry-content.excerpt,
.archive .x-main .hentry .entry-content.excerpt {
font-size: 16px;
}
3.) You may adjust the excerpt length in the theme options. Please go to X > Launch > Options > Blog > Content and set the excerpt length. Or you can set a manual excerpt instead. Excerpts are optional hand-crafted summaries of your content that can be used in your theme. Learn more about manual excerpts.
Hope this helps.
