Re: zooming font size on phone displays

The problem I have with pinch/zoom on mobile is that I then have to
pan/scroll to see everything.

For websites, I like to use a bookmarklet to increase (or decrease) the
fontsize of the page. It's not as straightforward as ctrl++ or cmd++ on a
desktop/laptop, and it's a little more work to set up, but it works well
enough. You have to add a bookmark to your browser then use the following
bookmarklets:

To increase the font size:
javascript:var
p=document.getElementsByTagName('*');for(i=0;i<p.length;i++){if(p[i].style.fontSize){var
s=parseInt(p[i].style.fontSize.replace("px",""));}else{var
s=12;}s+=2;p[i].style.fontSize=s+"px"}

To decrease the font size:
javascript:var
p=document.getElementsByTagName('*');for(i=0;i<p.length;i++){if(p[i].style.fontSize){var
s=parseInt(p[i].style.fontSize.replace("px",""));}else{var
s=12;}s-=2;p[i].style.fontSize=s+"px"}

I named my two bookmarklets "+++" and "---" and put them at the top of my
favorites. Having them be one character, just + or -, made the touch
target too small.

It doesn't work as well on my iphone because I can't see my favorite
bookmarks at the same time as the webpage. On my ipad, I went to safari
settings and enabled "show favorites bar". That way I can see "+++" while
on a website and can bump up the font pretty easily. On the iphone,
turning it landscape and touching the bookmarks icon will slide the
favorites menu from the left so it (cognitively) feels easier to use than
when in portrait mode.

I don't have an android phone but suspect its browser has a favorites
toolbar too.
