Button positioning for the Calculator

Button positioning for the Calculator

I have completed the Calculator project (actually I just realized it doesn’t like decimals…working on that). You can find my project here. I based the overall layout on the example solution.

I found the button placement to be a little tricky and would like to discuss the best way to position the buttons. This was my approach:

  1. Wrap all the buttons in a div and set its width to 300px

  2. Make the buttons 60px by 60px and leave 20px between them. I accomplished this by adding classes to the middle two columns and then setting the font size of the div to 0 (if this is not done there is extra whitespace).

  3. For the equals button, set its height to be 140px (60 + 20 + 60) and add vertical-align: top to its css.

  4. For the 0 button, set its width to 140px.

  5. Wrap the bottom two rows in a div and set its height equal to 160px

  6. wrap the 0 and . button in a span and give it the following css:

     position: relative;
     top: -80px;
    

This produces the desired layout, but I’m not overly fond of this approach, particularly steps 5 and 6. How would you accomplish a similar layout?

One thing I would suggest is this:

Your container div is already specified by px, so your elements inside can be defined as a percent. If you want to scale later on with a media query, then you need to only change the css for the larger box, and then those percentages inside will scale automatically.

I think I see why you are uncomfortable with your solution for 5/6, but I’m not sure. Simply moving the buttons down with “top: -80px” seems artificial? One solution could be to have your right column be one div and the rest of the buttons be a separate div. That way the extra tall equals button wouldn’t have to be accounted for, and the inline buttons (specifically the longer 0 button) would still wrap naturally.

Have you worked with display: flex much? I’m just starting to use it myself, so I can’t give much advice, but it might be able to handle this in a more natural fashion. The link is to css tricks, which seems to be a fairly straightforward guide.

Good suggestion. The layout of the calculator is simple enough that I don’t have any media queries but I will bear that in mind for future projects.

More or less. It’s not terrible, but I’m not 100% satisfied with my solution (if I was I wouldn’t have made this post in the first place :slight_smile:).

That would work. I don’t think I’ll change my code, but that’s a nice workaround.

Only a little bit. I had a feeling Flexbox would come up in discussion though.
