Hi @rafsanj24,

I hope you are well today and thank you for your question.

The space displayed above the slider is padding added to column so you can either remove that padding by editing the column in admin area or remove it by by adding the following CSS code in the Custom CSS code option of your theme on the below path.

Admin Area -> Appearance -> Theme Settings -> Custom Code -> CSS Code

.vc_column-inner.vc_custom_1510304186979 {
    padding-top: 0 !important;
}

You can hide those categories using Yellow Pencil editor as described in the following page.

Best regards,

that means i have to purchase Yellow Pencil  plugin ???  am i  right ?
will not i get that with your theme >?

Sorry I was confused the plugin comes bundled with Jevelin theme free of cost.

In the case of Gillion theme we can hide it developing custom CSS code.

Could you please share me the screenshots of sections from where you want to remove the categories so that I can help you?

Also please share me your site URL where it is displaying.

waiting for your response

Please share me your site URL where it is displaying so that I can help you to change it.

so the pencil editor plugin not comes with Gillion theme ? am i right ?

Yes you are right.

here i am sending the full screen short and i indicate all with mark that where and where actually i need help . please have look on the attachment .

That text is displayed by Blog Text Slider element of WPbakery page builder and they are post titles configured in the Blog Text Slider element so you can configure it as shown in the attached screenshots.

You can hide the categories by adding the following CSS code in the Custom CSS code option of your theme on the below path.

Admin Area -> Appearance -> Theme Settings -> Custom Code -> CSS Code

.blog-slider-item .post-categories-container,
.blog-slider .slick-arrow p,
.blog-page-list .post-categories-container {
    display: none;
}

As described in the above reply that those are not just text but they are post titles and titles of which posts to display there can be configured in the Blog Text Slider element.

In short you can’t change post title text but can configure in the Blog Text Slider element which post titles to display.

In your above shared screenshot you only displayed categories to remove from home page.

You can remove it from all other pages using below custom CSS code.

.post-categories-container {
    display: none !important;
}

I don’t see the issue on your shared site so could you please share me the specific page URL from your site where it is displaying?

Also does the issue only occur when you use custom CSS code orelse does it display fine?

This is because it is displayed in masonry style.

You can change its style in the theme Blog settings as shown in the attached screenshot.
