(1) Do you own the rights to the first background image? If not, you should use an image that you own the rights to.
(2) Related to (1), Iād suggest using a different image anyway, as the current photo is way too gloomy/moody. It might work as a portfolio image for a nature photographer, but an overly moody image like that doesnāt really have a place on a site for a Web developer. You should use an image that conveys either a neutral meaning or a bright/optimistic meaning.
(3) Your scrollspy doesnāt seem to work.
(4) IMO the tiles in your portfolio section are too big. You might consider condensing it down to a 2x3 matrix instead of the 3x2 matrix as it is right now, or alternately reducing the height of the tiles if you want to keep it as a 3x2 matrix.
(5) Code-related: your ātitleā tag is empty.
(6) Code-related: the contents of your H1, H2, and H3 tag arenāt semantic and donāt use the tags properly. The header tags are headersāyou should use them to sectionally divide the body of the entire page, not to arbitrarily visually differentiate lines of text. To style different lines of text, you should use SPAN instead. A more proper use of these tags would be to use H1 for the page title (something like your name), H2 for the āHi thereā, āAbout Meā, āPortfolioā, and āGet in touchā text, and H3 not at all (as you donāt have any content that calls for another header).
(7) Code-related: itās improper to use the H1 tag more than onceālike an ID attribute, you should have only one H1 on the entire page. You can have multiple H2 tags, but there should be only one H1.
(8) Code-related: you might want to consider reducing your tabs to indent 2 spaces, instead of 4: http://stackoverflow.com/questions/2167524/do-you-indent-your-html-code
(9) You should always run any HTML you write through the W3C Validator to ensure that itās error-free: https://validator.w3.org/
