Make Webpages Easier to Read
The iPhone 8 and iPhone 8 Plus include a reader mode that can make webpages easier to read. When you turn it on, the page is formatted to make the text easier to see and it also hides the ads.
Tap on the four lines to the left of the web address in Safari. This will turn the Reader mode on. From there you can tap on the "aA" to the right of the web address to open up more options.
In Reader mode, you can also change the font, the text size, and the background color. It's very similar to the options you have when reading a book on your iPhone.
You may not see all videos or photos in this mode, so toggle it off if you need to see that kind of multimedia.
