CSS Help « Gravity Support Forums

You can add this to your custom.css style sheet - customize the width to your preference.

.ginput_container textarea {width:200px!important}

I see that your form isn't getting the default styles. You're probably embedding it via the function call.

When using a Gravity Form in a sidebar widget or embedding it anywhere using the function call, you need to manually enqueue the scripts and CSS by placing a short script block in your theme's functions.php file.

wp_enqueue_script("gforms_ui_datepicker", WP_PLUGIN_URL . "/gravityforms/js/jquery-ui/ui.datepicker.js", array("jquery"), "1.3.9", true);

wp_enqueue_script("gforms_datepicker", WP_PLUGIN_URL . "/gravityforms/js/datepicker.js", array("gforms_ui_datepicker"), "1.3.9", true);

wp_enqueue_script("gforms_conditional_logic_lib", WP_PLUGIN_URL . "/gravityforms/js/conditional_logic.js", array("gforms_ui_datepicker"), "1.3.9", true);

wp_enqueue_style("gforms_css", WP_PLUGIN_URL . "/gravityforms/css/forms.css");

Without this, the conditional logic scripts, datepicker script, form CSS and other elements needed for the full form functionality aren't loaded.
