html - How to Make an SVG Image Dynamically Match the Height (1em) and the Baseline of Surrounding Text? -


is possible dynamically resize svg image (using html or css) match baseline , height of surrounding text?

something (the svg image being windows logo in situation):

image 1

image 2

the context clear images; want svg image match size of text no matter font face or font size viewer of page using.

if possible, should still match size of text if user zooms in page using browser’s zoom text only feature (like one):

support.mozilla.org/en-us/kb/font-size-and-zoom-increase-size-of-web-pages#w_how-to-only-change-the-size-of-the-text

i suppose that, effectively, want browser treat svg image if it’s text.

…i realize using web font may optimal solution in scenario, i’d rather avoid if can it. other being bit of ugly solution problem, creates new issues, like:

  • even if create web font myself, height of logo won’t (exactly) match em in every font in existence (although, @ least, sizes close)

  • there’s higher chance user have web fonts blocked on images

  • etc.

the naive answer set height of svg 1em. but, of course, want match x-height of font, not em height.

the news x-height consistent particular font, no matter how large is. once find right em value set svg size to, work whatever font size choose.

demo

svg.keyicon  {    width: 0.8m;    height: 0.8em;  }      .small  {    font: 24px arial;    color: black;  }    .large  {    font: 36px arial;    color: blue;  }
<div class="small">    press     <svg viewbox="0 0 100 100" class="keyicon">      <circle cx="50" cy="50" r="50" fill="currentcolor"/>    </svg>    key...  </div>      <div class="large">    press     <svg viewbox="0 0 100 100" class="keyicon">      <circle cx="50" cy="50" r="50" fill="currentcolor"/>    </svg>    key...  </div>

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
