Theme Horse

Hi Julien,
Go to the Dashboard -> Appearance -> Theme Options -> design options -> Custom CSS and add paste this CSS

#access a {
text-transform: none;
}

For your second question

We recommended not to change the code because if you change the code then while updating to our new version all your customisation code will be lost. So better make child theme and first unhook the functions and the edit the code.

As you have mentioned above that you don’t have any problem to change the code. Then its ok. The file is under you theme folder (interface pro) -> inc -> widgets -> interface_widgets

If you want to change the services widgets read more link path then, its on line no 342
Can you see this code ?

<a class="more-link" title="<?php the_title_attribute(); ?>" href="<?php the_permalink(); ?>">
 						<?php echo $options[ 'post_excerpt_more_text' ]; ?></a>

You may change here.

I can give you a something help better make it with child theme.
==> widgets child theme

In functions.php of the child theme, create your widgets and register them. Just copy the parent widget, change the name of widget like Theme Horse Child: Services Widget, make customisation and create your custom widget. If you do this, the widgets of parent theme and child both will appear. Use your custom widget of child theme instead of the parent theme.

Just making same file structure in the child theme like /library/widgets won’t overwrite the parent file. Hope this helps.

Thank you!
