That's great you'll be your daughter's biggest cheerleader no matter what she did. That is in the end what matters the most since the messages sent to girls can be pretty toxic. I saw a video on Russell Howard's channel about toys for girls are and the impact these messages have on girls. He particularly does this with the laptop examples. You can watch the video on Russell Howard's channel but it just shows how important it is for girls to hear messages that tell them to create, build and do awesome things no matter what they want to do.
As for CodeTips, definitely feature more content from female coders. Especially with the authors. You can do interviews with female coders or allow female coders to write a post teaching something coding related. Perhaps reaching out to other female developers or software engineers asking them to create content. You can do this very easily on Twitter. You can also do something for International Woman's Day and highlight women in the programming or do a celebration similar to what The Practical Dev does for #shecoded. #shecoded doesn't just encourage female developers to write posts but they will promote those posts the entire day.
Those are some of the suggestions you can start with. I just took a look at your site and that's some of the things I've noticed. Hope this feedback helps.
