Hello There,
Thanks for writing in!
1.) To change the navbar fonts, please go to the theme options, X > Launch > Options > Header > Link - Text.
2.) To make the text bigger, you can make use of the <span> tag and with an inline css just like this:
<p class="man">From an <span style="font-size: 24px; font-weight: bold;">organic</span> shape candle holder to a designer coffee table, all our clients get the best.
<br>We have to safeguard our planet’s decoration so we have to act responsibly; that’s why we promote the use of recycled materials and fabrication in an ethically managed cooperative guild.
</p>
3.) Please create a grid and select “Wilson” as your skin. The grid layout, you must select Coobles. For more information, please check out the documentation:
