Turn next and previous post links to theme buttons?

To clarify, do you want the design to look like that? If so, you'll need to use a Block Element - Post Navigation. Reference: https://docs.generatepress.com/article/block-element-post-navigation/

If you want it to stack like that on mobile, Ying's CSS should be good.

@Fernando,

Can't be it done using a CSS code? the Ying's CSS not working...

How did you add Ying's code? I can't see it added.

That design is a bit complicated to be created through CSS code. This would be out of our scope. To copy such a design with CSS, it would be best to reach out to a developer.

@Fernando,

Sorry, the code is working fine now on desktop and mobile, but I see an icon below the nav, how to remove it?

Also, how to remove underlining from the text?

For the icon, it's from this custom code you have:

.post-navigation .nav-next .next:after{font-family:GeneratePress;text-decoration:inherit;position:relative;margin-left:.6em;width:13px;text-align:center;display:inline-block;content:"\f105";-moz-osx-font-smoothing:grayscale;-webkit-font-smoothing:antialiased;font-style:normal;font-variant:normal;text-rendering:auto;line-height:1;speak:none}

For the underline, there doesn't seem to be any CSS adding the underline. Do you have Javascript causing this? Perhaps you can try #1 here: https://docs.generatepress.com/article/debugging-tips/

@Fernanod,

How to remove the icon CSS? I copy/pasted the following CSS from one of your posts...

/* Post Prev and Next Links */
#nav-below {margin-top: 10px;}
.nav-previous,.nav-next {position: relative;margin-top: 10px;}
.nav-previous,.nav-next {position: relative;}
#nav-below .nav-previous a,
#nav-below .nav-next a {display: block;padding: 20px 40px;background-color: #f8faff;border: 4px solid #7ea8fd;color: #0d3a93;font-size: 16px;}

#nav-below .nav-previous a:hover,
#nav-below .nav-next a:hover {background-color: #e7efff;}

.nav-previous .gp-icon,
.nav-next .gp-icon {position: absolute;top: calc(50% - 15px);left: 10px;font-size: 20px;font-weight:700;color: #fff;}
.nav-next .gp-icon {left: unset;right: 0;}
.post-navigation .nav-previous:before {
    content: "Previous Article:";
    display: block;
    font-size: 12px;
    text-transform: uppercase;
}

.post-navigation .nav-next:before {
    content: "Next Article:";
    display: block;
    font-size: 12px;
    text-transform: uppercase;
}

@media(max-width:767px) {
.single-post nav#nav-below {
    flex-direction: column;
}

.single-post nav#nav-below > * {
    width: 100%;
}
}

Look for the exact code I shared here: https://generatepress.com/forums/topic/turn-next-and-previous-post-links-to-theme-buttons/page/2/#post-2578208

It's the one adding the icon.

@Fernando,

I can't find the exact code in the CSS as you mentioned here - https://generatepress.com/forums/topic/turn-next-and-previous-post-links-to-theme-buttons/page/2/#post-2578208

There is some CSS from your home page paging nav that interferes with this.

Remove the CSS from this topic that you added.
Raise a new topic - so we don't keep spam notifying the OP.
And share the images of how you want it to look and we'll start over. Otherwise we will be adding more and more CSS
