Hello,We can provide custom css to force it to keep 4 column if needed.

Do you have a link to the page so we can check and confirm the portfolio type you are using and then provide the css.

Kind regards

Hello,

Try this custom css ( Cesis > General settings ) :

@media only screen and (max-width: 768px){  .cesis_isotope.col_6 .cesis_iso_item, .cesis_isotope.col_5 .cesis_iso_item, .cesis_isotope.col_4 .cesis_iso_item, .cesis_isotope.col_3 .cesis_iso_item, .cesis_isotope.col_2 .cesis_iso_item, .cesis_isotope.col_6[data-layout=packery] .cesis_iso_item, .cesis_isotope.col_5[data-layout=packery] .cesis_iso_item, .cesis_isotope.col_4[data-layout=packery] .cesis_iso_item, .cesis_isotope.col_3[data-layout=packery] .cesis_iso_item, .cesis_isotope.col_2[data-layout=packery] .cesis_iso_item { width: 25% !important; }

}

@media only screen and (max-width: 1024px){ .cesis_isotope.col_6 .cesis_iso_item, .cesis_isotope.col_5 .cesis_iso_item, .cesis_isotope.col_4 .cesis_iso_item { width: calc(100%/3); }

}

For the thumbnails it is possible but you need to modify the theme code directly, if you can tell me which thumbnails exactly I should be able to tell you which file need to be modified.Kind regards

Hello,

I am sorry our staff is currently limited because of the holidays but we should be able to get back to you the 31 or at the start of the year.

Sorry for the inconvience and thanks for your patience.

Kind regards

Happy new year too!

I am sorry but it seems to be a little complicated if you want to add a new thumbnail size for the portfolio.

A note from our developer :

You need to edit the cesis/functions/cesis_functions/cesis_thumbnail.php and the cesis/functions/cesis_vc_functions.php in order to achieve this.

I am sorry but our support doesn't cover modification of the template, if need you can use https://wpbuilders.co/ service by one of our developer.

I am sorry for not being able to help you this time.

Have a nice week!

Kind regards

You're welcome!

If you need help with the customization contact https://wpbuilders.co/

Devs from our team created this service so they are familiar with the theme.

Do not hesitate to contact us if you have more questions.

Have a nice day!

Regards.
