how to add custom html and css in wordpress
/* I have just tried running your code on a fresh WordPress install with the Neve theme installed. Its all working correctly, except do not use . container as a class for the flex box, instead use something like . container-flex. .container is already assigned to some HTML in the Neve theme. I was unable to gain access to the site you want to use this on. But if you just need to add this onto a page, use the Custom HTML block, paste in your HTML code and save the page. */ <span> <div class ="container-flex"> <div class ="box-zeeland" > Zeeland </div> <div class ="box-normandie" > Normandy </div> <div class ="box-roffa" > Rotterdam </div> <div class ="box-Valencia" > Valencia </div> <div class ="box-Adam" > Amsterdam </div> <div class ="overlay" > </div> </div> </span> /* Then click on Customize > Additional CSS, and paste your CSS code in there and click Publish. Then your code should work as intended.*/
